[M3devel] Fw: Re: Fw: UTF-16: Greek alphabet with CM3

[Olaf Wagner]

Hi Elmar Stellnberger,

I've forwarded your question to the m3devel mailing list; there has only
been one answer so far though (see below). Daniel is talking about using
some ISO-charset variant; I'm not sure if that is an option for you.

I myself would think it should not be too much work to adapt Trestle
and X for Unicode support, but then I haven't had a close look at the
code and surely won't have the time to do that.

I'm also unsure if UTF-8 might not be the way to go,

Olaf

Hi all:
I'm retired for Modula-3 work for now, but the ASCII table had codes for Greek alphabet are you sure you can't print that with ASCII?

Thanks in advance


PD: I  will have time In January, if you want I can help port your app (if it doens't have too much goto's)

I know that there have been controverse discussions about the right
way to do unicode support.

Is there any way to help Elmar Stellnberger with a quick solution?

Dear Supporters of CM3, Elegosoft

   Wanting to make use of CM3s new UTF-16 feature I have tried to use 
greek letters by VAL(945+code,WIDECHAR) where 945 is alpha and 946 is 
beta in the unicode table. However I soon had to notice that outputing 
widechars is not supported by Trestle which still seems to be based on 
X11R4. Some analysis of the problem has shown that TextVBT calls 
VBT.PaintText which does however use the CHAR type internally rather 
than Widechar calling PaintSub to output text instead of the X11R6 
function XDrawString16. Is it true that you plan real unicode support 
for CM3 or is there any way to hack the trestle toolkit into allowing 
X11R6 functions? If yes or no how could I convert current X11R6 includes 
for being used with Modula-3? Nonetheless I would really welcome true 
native utf-16 support (as nowadays given by the iso10646-1 X core fonts 
like also 'fixed') because that would be the only way to make use of 
utf-16 for Windows ports. Otherwise I will have to consider whether I 
can use Modula-3 at all for my current project which is about converting 
the automaton simulator www.elstel.org/coan from Object Pascal into a 
currently supported language and publishing it as open source.
Thanks a lot for your effort!

Yours,
Elmar Stellnberger
