The EscapeUriString method converts all characters, except RFC 3986 reserved and unreserved characters, to their hexadecimal representation. All Unicode characters are converted to UTF-8 format before being escaped.

This method assumes that stringToEscape has no escape sequences in it.

The string is escaped according to RFC 3986. See this RFC for a definition of reserved and unreserved characters.
