Bug#235998: partman: DOes not properly display the french E circumflex

I create build/needed-characters and put there a "fr" file which lists
all non ASCII characters we need for our language, and for debconf
templates (no, no Euro sign and so on).

We can then ask each language coordinator to create such file for
his/her own language. Sounds a bit overkill but this will help knowing
which language need which character.

This is of course targeted on ISO-8859-* (or even only ISO-8859-1)
based languages....

Be aware that the first character is the non breaking space. I did not
want to forget it.

The file is UTF-8 encoded.

If this scheme is OK to you, I can write a README file there and put a
note in doc/translations.txt as well as sending a mail to -boot about
this.
