Re: [PHP-DEV] Bug #6173: urlencode() doesn't respect locale From: Joey Smith (joey <email protected>)

Hmm...
I'm not sure that this is a bug.

RFC 1738 says:
URLs are written only with the graphic printable
characters of the US-ASCII coded character set.

I realize that urlencode() is not RFC 1738 directly,
but still...
