Can't change xlabel font because of diacritics (č, ř, š, ...)

8 views (last 30 days)
My language uses letters that use diacritics (č, ř, ž, ... ).
I tried to change font in my Matlab script to Latin Modern Roman, and it gave a following error:
Warning: Error updating Text.
String scalar or character vector must have valid interpreter syntax: čas (s)
> In defaulterrorcallback (line 12)
> In print (line 36)
The font was not applied. After I removed the č letter, everything went fine.
Any ideas?
The command I used was:
xlabel('čas (s)','Fontsize',fsz,'FontName','Latin Modern Roman')
Perhaps there is a different way.

I just get interpreter error messages. As far as I can tell, there are a number of TeX constructs that do not work in MATLAB.
For example, several \begin constructs that I find in TeX-specific documentation do not work; the only one I can get to work is \begin{array}
but I haven't seen a way to build macros in 'tex' or 'latex' interpreters. And 'latex' \usepackage is certainly not usable...
tex and latex in MATLAB have always been badly restricted.

The error you're seeing is because of the tex interpreter, although I don't reproduce it with the same characters. If you're not relying on the tex interpreter, you could try turning it off.
Note that in the example below I chose a font that I knew would be recognized in the browser, to check if the font is defined in your desktop version of MATLAB use the listfonts function.
xlabel('čas (s)','Fontsize',14,'FontName','Serif','Interpreter','none')
ylabel('čas (s)','Fontsize',14,'Interpreter','none')

I wonder whether you have configured
set(0, 'DefaultTextInterpreter', 'latex')
latex Interpreter can only handle US-ASCII
