URL encoding converts characters into a format that can be transmitted over the Internet. - w3Schools. So, "/" is actually a seperator, but "%2f" becomes an ordinary character that simply represents "/" character in element of your url.
Simple & Easy answer, The %2C means , comma in URL. when you add the String "abc,defg" in the url as parameter then that comma in the string which is abc , defg is changed to abc%2Cdefg . There is no need to worry about it.
is a reserved separator character that cannot appear unencoded in the name and value fields, it must be url-encoded as %3D : custom_field_id%5B%5D%3D10=custom_field_value_10%3DFull-time. It is the receiver's responsibility to url-decode the submitted data before then processing it.
%E2%80%8B is the code for a "ZERO-WIDTH SPACE" character. It has probably been inserted without you noticing it somehow, you probably can't see it in your code, but it is here. I recommend completely removing the string (including the surrounding quotes!) where the URL is defined and re-write it.
Your computer's URL code (or Internet address, or IP address) is the address that other computers enter in to access your computer across the Internet. This is a four-section number, such as 123.456. 78.90.
Open a browser window, and enter the address http://www.apache.org// (two forward slashes at the end). You will get the home page. Replace the forward slash at the end with %2F (url encoded slash) so address becomes http://www.apache.org/%2F. The web server will now respond with a “404 (Not Found)” response code!
As per this answer over here: str='foo%20%5B12%5D' encodes foo [12] : %20 is space %22 is quotes %5B is '[' and %5D is ']' This is called percent encoding and is used in encoding special characters in the url parameter values.
& is HTML for "Start of a character reference". & is the character reference for "An ampersand". ¤t; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this).
A UTF-8 byte sequence "E2-80-A8" (U+2028, LINE SEPARATOR), a perfectly valid character in a Unicode database. However, that sequence represents a line-separator (Yes, other then "0A").
What character is E2 80 8B?
The difference between encodeURI and encodeURIComponent is encodeURIComponent encodes the entire string, where encodeURI ignores protocol prefix ('http://') and domain name. encodeURIComponent is designed to encode everything, where encodeURI ignores a URL's domain related roots.
(“3D” is the hexadecimal representation of the equals sign.) If you believe this is the problem with your HTML, try putting an equals sign anywhere in the rest of the HTML code to make sure that the email is being properly decoded (put in something like “2 + 2 = 4”).

On your computer, go to google.com. Search for the page. In search results, click the title of the page. At the top of your browser, click the address bar to select the entire URL.
How to Find the URL - YouTube
- Open the Free & Online URL Decode Tool.
- Enter the URL, or use the "Load from URL" or "Browse" option for getting the encoded URL.
- Click on the "URL Decode" button in case you want to decode the encoded URL.
- Click on the "URL Encode" button in case you want to encode the decoded URL.
URL Encoding (Percent Encoding)
URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
Why do we need to encode? URLs can only have certain characters from the standard 128 character ASCII set. Reserved characters that do not belong to this set must be encoded. This means that we need to encode these characters when passing into a URL.
Special characters in URLs are usually expressed using the percent sign and a sequence of numbers. For spaces, this is %20. For frequently used special characters, there is an abbreviation of this notation. For spaces, the plus sign (“+”) is defined for this purpose.
How do I encrypt an HTML URL?
URL encoding replaces non-ASCII characters with a "%" followed by hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign, or %20.

Using URL escape characters with the URL API.
| Character | Escape Character |
|---|---|

& (&) - Required, so that a browser does not misinterpret it as the beginning of an entity. < (<) - Required because otherwise a browser could misinterpret it as the beginning of a tag. > (>) - Required because otherwise a browser could misinterpret it as the ending of a tag.
& is the html entity (encoded form) for & , used to describe an ampersand in languages where an ampersand actually means something, like XML.
Etymology. The term ampersand is a corruption of and (&) per se and, which literally means "(the character) & by itself (is the word) and." The symbol & is derived from the ligature of ET or et, which is the Latin word for "and."
E2 80 99 is the sequence of hex values that encode a right single quotation mark (') in UTF-8.

UTF-8 is a multibyte encoding able to encode the whole Unicode charset. An encoded character takes between 1 and 4 bytes. UTF-8 encoding supports longer byte sequences, up to 6 bytes, but the biggest code point of Unicode 6.0 (U+10FFFF) only takes 4 bytes.
Unicode. In Unicode, the LRM character is encoded at U+200E LEFT-TO-RIGHT MARK ( ‎). In UTF-8 it is E2 80 8E .
It is a character encoding issue. Whom ever is sending the mail is using a character set that is not appropriate. View menu (Alt+V) > character encoding and select UTF-8 or unicode should see the correct display.
Is a UTF-8 character?
UTF-8 (UCS Transformation Format 8) is the World Wide Web's most common character encoding. Each character is represented by one to four bytes. UTF-8 is backward-compatible with ASCII and can represent any standard Unicode character.
The encodeURIComponent() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two "surrogate" characters).
- var set1 = ";,/?:@ &=+$"; // Reserved Characters.
- var set2 = "-_.!~*'()"; // Unescaped Characters.
- var set3 = "#"; // Number Sign.
- var set4 = "ABC abc 123"; // Alphanumeric Characters + Space.
- console. log(encodeURI(set1)); // ;,/?:@ ...
- console. ...
- console. ...
- console.
Depending on what you need to do, there are 2 JavaScript functions that will help you. The first is encodeURI(), and the second is encodeURIComponent(). Note: you might read about escape(), but that is deprecated and should not be used. Those 2 methods differ in which characters they do encode.
9 votes. “print” treats the % as a special character you need to add, so it can know, that when you type “f”, the number (result) that will be printed will be a floating point type, and the “. 2” tells your “print” to print only the first 2 digits after the point.
If you want to avoid double encoding the links you can just use urldecode() on both links, and then urlencode() afterwards, as decoding a URL such as "https://www.cool.com/cool beans" would return the same value, whereas decoding "https://www.cool.com/cool%20beans" would return with the space.
Experiments of Mixing Slashes
And found that all those browsers accept URLs written with forward slashes ( / , the correct form), URLs written with backslashes ( \ , an incorrect form) and URLs written with mixed slashes in their path part ( / & \ , another incorrect form).
A URL is composed of a limited set of characters belonging to the US-ASCII character set. These characters include digits (0-9), letters(A-Z, a-z), and a few special characters ( "-" , "." , "_" , "~" ). When these characters are not used in their special role inside a URL, they must be encoded. Question mark (“?”)
0 votes. %s means its a string, %d is an integer, %f is floating point number.
printf("%. 2f", value); The %. 2f syntax tells Java to return your variable (value) with 2 decimal places (.
What does %f mean C?
| Specifier | Used For |
|---|---|
| %f | a floating point number for floats |
| %u | int unsigned decimal |
| %e | a floating point number in scientific notation |
| %E | a floating point number in scientific notation |
So you can test if the string contains a colon, if not, urldecode it, and if that string contains a colon, the original string was url encoded, if not, check if the strings are different and if so, urldecode again and if not, it is not a valid URI.
Why do we need to encode? URLs can only have certain characters from the standard 128 character ASCII set. Reserved characters that do not belong to this set must be encoded. This means that we need to encode these characters when passing into a URL.
kinda de-facto standard yes. but only in modern browsers. its done for user convienience, so you can put utf8 charactesr in an url and its still pretty to the human eye. however please be aware that the text is actually still encoded and will be transmittet/requested encoded, it is only displayed decoded.
Forward slashes are used for web URLs because the first webservers were running Unix and that's what Unix uses for a directory separator. Since early websites just mapped onto the directory structure, that was the obvious thing to do. Backslash is used on Windows computers because that's what was used on DOS.
The backslash (\) is mostly used in computing and isn't a punctuation mark. The forward slash (/) can be used in place of “or” in less formal writing. It's also used to write dates, fractions, abbreviations, and URLs.
The forward slash (or simply slash) character (/) is the divide symbol in programming and on calculator keyboards. For example, 10 / 7 means 10 divided by 7. The slash is also often used in command line syntax to indicate a switch.
- The control characters (chars 0-1F and 7F), including new line, tab, and carriage return.
- "<>^`{|}
A URL in your data feed is badly formed or contains invalid characters. There are several common reasons why you might receive this error: Your URLs contain spaces or symbols. Our system won't be able to process URLs containing spaces or certain symbols.
URL escape codes for characters that must be escaped lists the characters that must be escaped in URLs. If you must escape a character in a string literal, you must use the dollar sign ($) instead of percent (%); for example, use query=title%20EQ%20"$3CMy title$3E" instead of query=title%20EQ%20'%3CMy title%3E' .
