Details:
I have a manual for a free software package, which is written in utf-8
encoding. Export to text/info/html works as expected, but I have to add the
following to be able to export it to pdf:
@tex
\DeclareUnicodeCharacter{00A0}{\ }
… several other characters …
@end tex
This has worked for me for a while, but it breaks on later Texinfo versions
with the following error:
/path/to/octave-interval/octave-interval/doc/manual.t2d/pdf/xtr/manual.texinfo:8:
Internal error, already defined: 00A0.
\DeclareUnicodeCharacter ..., already defined: #1}
\fi \expandafter
\globalle...
l.8 \DeclareUnicodeCharacter{00A0}{\ }
As far as I have found out, there have been the following relevant changes to
TexInfo in the meantime: (1) The character 00A0 has been declared globally,
which is great, and (2) commit 6086 has introduced error checking, which
forbids re-declarations for the same character.
Now I have the problem that I have to remove the DeclareUnicodeCharacter
commands, to be able to compile under recent TexInfo versions, but then it is
no longer possible to compile under old TexInfo versions (for example in
Debian Jessie).
Could you remove the above error message, or at least make it a warning
message? Then my TexInfo document would be backwards compatible.
