Hello everyone

I have a file in which some segments contain Chinese characters. I need to identify these segments, so I'm hoping I can use a search for the specific Unicode characters that are Chinese. Can anyone clarify for me what is the UTF8 character range for Chinese characters?

Thanks
Samuel

However, I discovered that searching for the presence of all of these characters would be very inefficient, so instead I converted all my source text to one character per line and then removed duplicate lines, to get a list of all characters used in the source text. Then I just deleted non-Chinese characters, and thus had a much smaller list of characters to search (and no need to search hexadecimally either).

Here is the range that I use (even though you have already found, maybe, it will be handy):

Thanks, I'll give that a try as well (then I can use regex).

As it happens, my source text contained only about 1000 distinct Chinese characters, so testing for each of them one by one across 2000 segments was doable and took about 20 seconds only (not including the time it took to script it in AutoIt, of course). I'm curious if a regex approach would be quicker (not counting preprocessing time).
