Documentation
URI-encode STRING and return the result.
If STRING is multibyte, it is first converted to a utf-8 byte string. Each byte corresponding to an allowed character is left as-is, while all other bytes are converted to a three-character string: "%" followed by two upper-case hex digits.
The allowed characters are specified by ALLOWED-CHARS. If this
argument is nil, the list url-unreserved-chars determines the
allowed characters. Otherwise, ALLOWED-CHARS should be either a
list of allowed chars, or a vector whose Nth element is non-nil
if character N is allowed.
