Hi there,

I started looking at OM today as an alternative to Dymola, for a mechanical engineering class in which I teach Modelica (as a TA).

Is it correct that OM cannot handle non-ASCII characters (ü, ä, ö, ß and so on) in path names, file names, variable annotations or any place?? When I load and check a model, everything is fine, but when I press the little green button to start a simulation I get an error message that reads:

"Process crashed throw    | [line] 255 | [file] simulation/simulation_input_xml.cpp | simulation_input_xml.cpp: Error: failed to read the XML file Exercise4.MainModel_init.xml: not well-formed (invalid token) at line 171"

where line 171 of the respective file is description = "Ůderung der Federl寧e m"

That line contained a German text that said "Änderung der Federlänge m" and is displayed correctly in the OMEdit model editor window. Somewhere though the program that wrote the XML file screwed up the non-ASCII characters Ä and ä.

It seems to me that this should be rather easy to fix, no?

It may be a trivial issue on one hand from a programming point of view ("just don't use those characters"), but on the other hand, it's extremely annoying from a user point of view when you already ~100 exercises that all have such characters somewhere. I thought the days where you should stick to ASCII characters and limit file names to 8 characters were long gone.
