Two things: This doesn't work, you have to use `chr(hex($2))`otherwise the numbers are converted as integer values and not hex! You don't need two pairs of capturing parens, this is unnecessary extra work for the regex engine. So the correct solution is `s/\[0x([a-f0-9A-F]{1,2})\]/chr(hex($1))/eg;` -- Hofmator	[reply] [d/l] [select]
