Re: XML to .ly and Lilypond, again

[Leszek Wroński]

Hi Robert,

thanks! I tried your file and I get similar messages:

-----------------
musicxml2ly: Reading MusicXML from Kyrie_copy.xml ...
musicxml2ly: Converting to LilyPond expressions...
(....)
musicxml2ly: Output to `Kyrie_copy.ly'

------------------

I'm using Ubuntu 16.04 64 bit Python 2.7.12, and Lilypond 2.19.48.

So is it the case that musicxml2ly is trying to apply the ''utf8'
codec' to the whole file while parts of it are conded in utf16?

Cheers,

Leszek.
