yes, nothing substantial as far as I have been able to figure out, or it is
related with the current project.

In order to have a development path, we intended to limit the initial support
to single voice music.
We currently have a library of around 1000 songs with both single voice music
versions, as well as four part choir versions and accompaniments.
This library was made to work with 2.14 and it looks like it might be a rather
complex process to convert everything.

The Guile documentation suggest loading unicode support through (use-modules
(ice9 unicode)) but that module is not part of Guile as distributed with
Lilypond...
At the same time this makes me wonder how complex it would be to update our
library. Nevertheless, our implementation should run on a "normal" distribution
of Lilypond. So, for the moment the question still stands: how could I deal
with this? Is it possible to add the unicode module to Lilypond somehow?
I checked the distribution for guile 1.8.7 and couldn't find a unicode.scm file
in the ice9 folder, nor a iconv.scm for that matter.
cheers
