Thanks for your answers.
I'm not expert in the technical internals of LilyPond and/or LaTeX,
but I'm pretty sure the problem could be solved in LilyPond.
Let's have a look of how LilyPond-embedding in LaTeX works:
LaTeX itself knows nothing abount LilyPond and how to interpret *.ly files.
In fact, die LilyPond-embedding commands like "\lilypondfile" are not
valid LaTeX syntax and end in an error of you try to interpret it with
To solve that, LilyPond provides a precompiler called "lilypond-book".
If you compile *.tex files with it, it will search for
LilyPond-embedding commands, interpret the LilyPond content, generates
vector graphic (*.eps) files for each line of the score and rewrites
the *.tex file.
The resulting *.tex file contains commands for embedding the generated
These files have no need to know how these graphics where generated,
they're just embedded graphics and that's the reason why you could
interpret that correctly with LaTeX.
Back to the topic:
It's possible that the problem is a LaTeX issue.
Maybe lilypond-book generates based on the original filename the
precompiling-objects (*.eps grahics and so on) with special characters
in the filenames which LaTeX can't handle.
But I guess LilyPond don't have to.
The resulting files of the lilypond-book precompiler are just
temporary objects and it's not relevant for the end-user how they're
So the precompiler could generate these tempoorary objects without any
special characters in it and voilà... LaTeX will not have any problems
with them. :)
To the argument "just don't use special characters becaus of the
possibility to switch the file system":
Yeah, you're right.
But file systems which can't handle special characters in filenames
are old file systems.
Most modern computers don't use file systems which can't handle that.
It's usual as computer user in 2018 to use filenames with special
characters in it.
So why should LaTeX/LilyPond be an exception?
Why not just enhance the products to fit the user's needs?
Prevent from using special characters in filenames is just a
workaround, not a solution.
