From 50533135622a80b0326c7e93067e136072bef5eb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 8 Jul 2017 10:59:19 +0200 Subject: urlmatch: use hex2chr() in append_normalized_escapes() Simplify the code by using hex2chr() to convert and check for invalid characters at the same time instead of doing that sequentially with one table lookup for each.
