we all need to trim - and trim pro




How often do you find that you need the Advanced portion? My personal trim looks like the first line of your code and seems to be fine... is this more of an international concern or...? when do you see those characters?


Advanced portion, not often mainly with different char sets or content that's been c+p'd from word documents; hence why I made it optional. However the last thing you want to be doing is trying to work out that your whitespace didn't trim because it's got a chinese ideographic space instead of a normal one.


Aaahhh, the "paste your doc here" option, clean and post, I get it.
