Extracting an UTF8 char number with Tilde [SOLVED]

[atout66]

Hi to all,

I have a field in which there are two UTF8 chars: <ʃ> and <ɑ̃>
I have this script:

Code: Select all

on mouseUp
   set the useUnicode to true
   answer charToNum(the unicodeText of last char of fld "leTest")
...

If I ask for the FIRST char, it's OK; it returns <643> which is the correct number.
But if I ask for the LAST char <ɑ̃>, and other last chars like <ɛ̃> or <œ̃> or <ɔ̃>, I get always <771> !

Could you explain me what am I doing wrong ?
I notice that the problem occurs always with the "tilde" char...

Thanks in advance.

Hi to all,

If this problem can not be resolved, I would suggest that it be placed in the bug report section, what do you think?

Kind regards.

Hi Atout66

I think you will find it worth having a look at Fraser's latest blog posting about Unicode http://livecode.com/blog/2014/04/02/exa ... ting-text/

I see you are developing with LiveCode 6.5.2 so to be able to use the new Unicode goodness you'll have to upgrade to LC 7

Thanks Dave for your link. I give it a look right now.

Hi atout,

771 is the "COMBINING TILDE"
see:
http://www.fileformat.info/info/unicode ... /index.htm

so instead of 2 you have 3 chars, the last one is the combining tilde.

Again I don't know anything about unicode.

But here is a littel stack that shows the numToChars and the html representation of
ʃɑ̃

Kind regards
Bernd

Thanks for your help Bernd
Your approach is very interesting.
I'm going to see how to deal with it because my upgrade with LC7 is presently not really successfull

Kind regards.
