Using Matlab compiler, accents are replaced by question marks.

Hi,

I have a tiny problem: in French, some words have accents. After compilation with Matlab compiler, accents are replaced by question marks. How can I solve this problem? Thank you for any help you can offer.

Can you show us some example ?

If you can release the sample code of your program it will be useful to understand the problem.

Thanks!

Hi GK,

For you to better understand, here is the lines code in my script (Matlab 2009a)

uicontrol(gcf,'style','push','pos',[xx1 yy1 dxx dyy],'String','Signaux déterministes',...
    'FontSize',taicarb+3,'FontWeight','bold',...
    'callback',['set(objsideal,''visible'',''off''),menu=1;,coulfenetre=coulde;,',...
    'set(gcf,''WindowButtonMotionFcn'','''');SIDEALdeChoix'],...
    'enable','on','backgroundcolor',coulde);

uicontrol(gcf,'style','push','pos',[xx2 yy2 dxx dyy],'String','Signaux aléatoires',...
    'fontsize',taicarb+3,'backgroundcolor',coulal,'FontWeight','bold',...
    'callback',['set(objsideal,''visible'',''off''),menu=2;,coulfenetre=coulal;,',...
    'set(gcf,''WindowButtonMotionFcn'','''');SIDEALal'],'enable','on’);

As you see, there is an ” é ” in the lines code for the push button names "Signaux déterministes" and "Signaux aléatoires". But the ” é ” is replaced by a question mark after running the script as you can see in the screenshot below.

Thanks for your help

Best regards

Rodrigo

Did you manage to solve this? I am facing the exact same problem now.

try using the ascii code for the letters that you want to be displayed, e.g.

disp(strcat('d',233,'terministes'))

déterministes

[Marc Raventós Tato]

Thanks, but the point is I used to compile this in previous versions of matlab (2012 vs 2022) and it accepted the french text without calling the ascii symbol.

[Constantino Carlos Reyes-Aldasoro]

I had similar problems changing from Mac to PC and between versions. But since using ASCII, even if it is a slight complication, I have not had those problems.

In r2012 you got lucky that the characters you were interested in happened to be representable in 8 bits in your default character set. In current versions, utf-8 encoding is used so multibyte encoding is used. Apparently the compiler is not expecting utf-8 encoding.
