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: string
the unescaped input string.
reserved_chars_allowed: string
a string of reserved characters that are allowed to be used, or null.
allow_utf8: boolean
true if the result can include UTF-8 characters.
Returns string
an escaped version of unescaped. The returned string should be freed when no longer needed.
Escapes a string for use in a URI.
