Unicode in scripting

Don, I just tried Muroph's Tag Manager v2.2, and encountered the above error - After processed line #23, the first keyword 'input' of line #24 was broken into lines #23 and #24, as well as the 'replace' in line #25, 'substr' in line #26, etc.
After replaced ▲ and ▼ in line #23 (in raw script, they're in lines #190, #191, #211 and #212), this script runs well. So I guess Unicode is the cause of this bug.

Yes, looks like. Currently no idea how to fix that because I don't even know exactly where/why the script was broken. It seems that the initial line parsing already chokes but why is "input" broken between "in" and "put"... What happens if you put any other Unicode character there -- same error?

Test 1:

Code: Select all

    $a = "▲";
    msg "test";

Raw view of the first test file in MBCS system:

My guess: You can see the MBCS string '$a = "▲";' takes 10 bytes in the raw view, but there are actually 9 Unicode chars after it's read into memory. Extra chars (from next line) will be read if using the byte number to break lines.

Thanks, really interesting! I forgot that there are Unicode that resolve to 2 chars when converted to ANSI.

Looks like I have to rewrite a couple of heavily used functions.
