The percentage   sign followed by two hexadecimal numbers  UTF-8 character representation  typically denotes a string which has been encoded to be part of a URI   This ensures that characters that would otherwise have special meaning don t interfere   In your case  20 is immediately recognisable as a whitespace character - while not really having any meaning in a URI it is encoded in order to avoid breaking the string into multiple  parts    Don t get me wrong  regex is the bomb  However any web technology worth caring about will already have tools available in it s library to handle standards like this for you   Why re-invent the wheel      var str    xPasswords 20do 20not 20match   console log  decodeURI str         xPasswords do not match    Javascript has both decodeURI and decodeURIComponent which differ slightly in respect to their encodeURI and encodeURIComponent counterparts - you should familiarise yourself with the documentation
