character encoding of texinfo_document pot file

[Federico Bruni]

Hi

while updating the italian file of texinfo_document and checking other 
languages (french, german) I found out some inconsistency in the 
character encoding.

The pot template is ASCII:
$ file texinfo_document-5.0.pot
texinfo_document-5.0.pot: GNU gettext message catalogue, ASCII text

Some languages have kept the ASCII, even languages which would need a 
better encoding (like french, which had to use crazy characters).
The file I submitted years ago is UTF-8. I guess that my PO editor 
changed it automatically. Same for other languages.

So I think that we can safely use UTF-8.
Maybe the pot file should be encoded as UTF-8 in first place, in order 
to avoid any problem for translators?
