    Question characters allowed in urls

    does anyone know where there is a list of all the characters that are allowed in url's? Are brackets and underscores allowed like this url:

  2. #2
    As found in RFC 1738 documentation

    "Many URL schemes reserve certain characters for a special meaning:
    their appearance in the scheme-specific part of the URL has a
    designated semantics. If the character corresponding to an octet is
    reserved in a scheme, the octet must be encoded. The characters ";",
    "/", "?", ":", "@", "=" and "&" are the characters which may be
    reserved for special meaning within a scheme. No other characters may
    be reserved within a scheme.


    Thus, only alphanumerics, the special characters "$-_.+!*'(),", and
    reserved characters used for their reserved purposes may be used
    unencoded within a URL."

    Moreover, this link will be helpful also, URL Character Encoding Issues are described :

    Url can contain various special characters. However, you should try not to use special characters. Take for example there is a page

    1. website/index?i=4950945840938
    2. website/about_me

    I am sure option two will look more appealing to the end users.

    Avoid using special characters in url to make your url more appealing to both users as well as search engines.
