Ola,

Fixing IupConfig() will help a lot. I was doing my own custom ini files but it
is far easier and the code is far more readable when using IupConfig().


So thanks for that.


Microsoft has both a #pragma and a function() for setlocale. I vaguely recall
using setlocale() and either I missed something or there was a problem with it
because I abandoned that idea. Actually I think I missed something, so I think
I need to try this out in my code again. If it works, I think that would be
the best all around solution. I think even the clipboard should work with that
and I wouldn't even have to translate any documents as Windows would do it for
me. So that sounds like a good solution for internationally-compatible apps.


I will report back to you how well setlocale() works, and if works well, could
I recommend that you record this solution in your online help file some place
where it is easy to see and find, say like Product --> International
Considerations or something like that? I think it is that important.


"If you decide to use this feature, another interesting option is to set the
console code page to UTF-8 executing 'chcp 65001' on the command line"


That is not a simple thing to request customers to do because Windows doesn't
properly support UTF-8 on the console unless you do this:

  Hi,


  I wrote a test that don't even use IUP, just to test fopen with UTF-8. It is
attached. I found out that it worked using setlocale only in Visual Studio
2017. It seems to be a new feature. I decide to describe this in the IUP
documentation:


---------------------------------------------------------------------------------------------
Notice that IUP, CD and IM libraries use the fopen based functions to read and
write files. In Windows fopen expects the filename string in the ANSI encoding
by default. If your filename, including the path, has characters that can not
be converted to ANSI, fopen will fail to open the file. In Windows we could
use _wfopen combined with UTF-8, but this is a Microsoft only function and
most of fopen usage in these libraries are in portable modules. This is an IUP
limitation in Windows. 
The simple workaround is to not use special characters in folders or files
name in Windows... Legacy applications will also have the same problem.
Another option is to call:
 setlocale(LC_ALL, ".UTF8"); But it will work for fopen only in Visual Studio
2017 or newer Microsoft compilers (setlocale will return NULL on other
compilers). fopen will successfully open the file if filename is an UTF-8
string, even with special characters. So you will be able to set both UTF8MODE
and UTF8MODE_FILE to YES.
If you decide to use this feature, another interesting option is to set the
console code page to UTF-8 executing "chcp 65001" on the command line. This
will allow your printf output to be properly displayed when using UTF-8
strings. This feature actually works for all Microsoft compilers in Windows,
and for MingW, even when setlocale returns NULL. Notice that some font
packages must be installed for this to fully work for all characters (for
instance Chinese, Japanese and Korean, along with some symbols too).
 
---------------------------------------------------------------------------------------------


  Yes, this is all an IUP limitation because its external API do not support
Unicode. 


  I also fixed a bug in IupConfig to handle the case where the system folder
has special characters, but they can be converted to ANSI. I was not doing
that conversion. Just committed to the SVN.


Best,
Scuri

Hi Antonio,


The following code:


 config = IupConfig();
 IupSetAttribute(config, "APP_NAME", "xyz");
 IupConfigLoad(config);


only seems to work if the current directory has no atypical (non-English)
characters in it, e.g. -- "E:\My\Files" vs "E:\My…\Files". I am using the
English version of Windows with code page 1252. Iup crashes at IupConfigLoad
within the function IupLineFileClose. The character "…" is Unicode codepoint
2026 (which translates to UTF-8 as 0xE2 0x80 0xA6).


Regards,
Andrew
