Hi, just to confirm my understanding about some previous items.

So making lilypond more locale-independent as David suggested in another message, and removing the setlocale call, could fix this too. For the time being I am overriding LC_NUMERIC in a few places: https://ao2.it/tmp/lilypond-guile2/patches_2016-11-19/0007-Print-floating-point-variables-using-a-period-as-the.patch > 2.

For now I am hardcoding the Latin1 encoding for the postscript output: https://ao2.it/tmp/lilypond-guile2/patches_2016-11-19/0008-Fix-the-encoding-of-the-postscript-output.patch But could dropping the (setlocale LC_ALL "") help here too? Or would it be better to use a binary port for output as well, to be safe?
