You mean in the path? In the path I suppose I should permit quite a
few more characters (I forgot 0-9 too). This makes the expression:
$expr =
'[a-zA-Z0-9]{1,10}://[a-zA-Z0-9.-]+[\p{L}0-9!$%&\\()+-./;=^_~]*|mailto:[EMAIL
PROTECTED]',

This will be used to pick out URLs in Creole Wiki markup. Which
incedentally is not supposed to match characters that can occur
naturally at the end of a sentence (,.?!:;"') so I guess I need to
leave out '.' and ';' for my particular application.
So given markup:
Please visit
http://www.yahoo.com/usèrs+100%&lusers$/~jerry/y_a-n.g/Yahoo;=^(!)foo.
The regex should match (minus the dot at the end):
[http://www.yahoo.com/usèrs+100%&lusers$/~jerry/y_a-n.g/Yahoo;=^(!)foo]
although in practice a URL this crazy should probably be formalized
with square brackets as defined by Creole for links.
