Re^2: CR-LF Newlines as 2 distinct characters

My problem has been integrating "my" newline sequence with the rest of the string, which also needs to get mangled. If I stringify it all as is, the CR-LF gets treated as a single character instead of being split with a \x00. If I pre-treat the newlines(s/\n/\x{0D}\x{00}\x{0A}/g) , it gets an extra \x00 in between when I mangle it.
As you suggest, I'll try a more explicit approach.

Ah, I see. I don't know what you need to "mangle", exactly, but since you seem to have UTF16-like representations of purely 8-bit chars, you might take a risk and do `s[\x00(?<!\x00)][]gs;` on the way in (0) to make a "real ASCII" string. You can then mangle the 8-bit ASCII string comfortably. Then do something like this on the way out: `$str = join( '', map{ "\x00$_" } split('',$str) );` [download] That should pad you appropriately. It's cheating, but it might work. [0]: The negative lookbehind is to make sure a "\x00\x00" doesn't get chopped away; it's untested, though. <–radiant.matrix–> A collection of thoughts and links from the minds of geeks The Code that can be seen is not the true Code I haven't found a problem yet that can't be solved by a well-placed trebuchet	[reply] [d/l] [select]
