Additionally, url's cannot contain spaces and are usually converted into either a " " or a %20. the browser will encode according to the character set in the document which is usually utf 8.

Utf 8 is variable width character encoding method that uses one to four 8 bit bytes (8, 16, 32, 64 bits). this allows it to be backwards compatible with the original ascii characters 0 127, while providing millions of other characters from both modern and ancient languages. There two steps in which url escape online works. in first step the all characters in the string separated using utf 8 encoding. convert each character that are not ascii letters into hexadecimal values. please check the table below to find out the backend key code against each charset. To quickly decode, even when you do not know how the string is encoded, use the free online service for determining and converting encoding. this service is copied from here 0xcc jsescape .

This is a bad solution, because it requires hardcoding every character. this problem is exemplified by your code missing the often used %20 escape sequence. Let's say i open a webpage with some unicode characters, say, cyrillic, in the address like this: when i try to copy it from the address bar somewhere else, it becomes unreadable rubbish: i guess this is for compatibility. however for readability i want to copy it straight away with proper unicode characters. 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.
