Simulation fails with Modelsim with special character in path

[magnmaeh]

I assume the issue is the same as #565, just the problem is with special characters like "æ" and not space. The two first lines have � - this should be "æ".

Output log:

Tested with Questa, GHDL, Riviera-PRO, Active-HDL, and NVC under windows and only NVC can handle this without problems. The tools fail in various ways but GHDL is very explicit about the problem:

error: invalid character not allowed, even in a string

I think this is a limitation that we will have to live with.
