Weird interference between OLL, input mode, note name language

[Simon Albrecht]

Hi everyone,

I have had a very weird error pop up, which doesn’t appear to be related 
to a specific LilyPond version, nor was it triggered by any recent 
update to OLL (though I’m using chordmode very rarely):

In the following snippet,after loading the core package loader from 
openLilyLib,Lily won’t recognise the changed note name language inside 
any explicit input mode.

%%%%%%%%%%%%%%%%%%%%%%
\version "2.23.5"

\language "deutsch"

\include "oll-core/package.ily"
<<
  \chordmode {
    h b % h isn’t understood
  }
  \notemode {
    h b % h isn’t understood
  }
  {
    h b % h is understood
  }
>>
%%%%%%%%%%%%%%%%%%%%%

I attach the package.ily file from openLilyLib—I can’t see anything in 
there which might cause this odd behaviour…

Best, Simon
