Uri.escapeString

string escapeString(string unescaped, string reservedCharsAllowed, bool allowUtf8)

Escapes a string for use in a URI.

Normally all characters that are not "unreserved" (i.e. ASCII alphanumerical characters plus dash, dot, underscore and tilde) are escaped. But if you specify characters in reserved_chars_allowed they are not escaped. This is useful for the "reserved" characters in the URI specification, since those are allowed unescaped in some portions of a URI.

Parameters

`unescaped`	the unescaped input string.
`reservedCharsAllowed`	a string of reserved characters that are allowed to be used, or null.
`allowUtf8`	true if the result can include UTF-8 characters.

Returns

an escaped version of unescaped. The

returned string should be freed when no longer needed.
