Ah, you should send that to Dave, so he can put it in the brltty
archive, as text.fr-iso15.tbl, or maybe better with the formerly
proposed convention: text.fr_FR at euro.tbl

Well, I guess it only works because brltty uses it as a iso1 table, and
carelessly use your euro sign for character 160, which indeed works.
(see ScreenDrivers/Linux/screen.c for details, setTranslationTable() for
instance. You may also try to run brltty with a -l 7 parameter to be
able to see character mapping errors).

But with a frame buffer or anything that lets brltty know that what
really needs displayed is a euro (unicode for instance), brltty doesn't
know that it can use the representation of character 160 in your table:
in iso1, character 160 is "monetary symbol", not "euro" (iso15).

The solution would be that the .tbl format include a way to tell which
8-bit character set it is intended for. For instance, the Czech table
needs be declared as iso2 for proper unicode support. But then the core
itself would need to know about unicode, which is not the case yet.

Dave, I guess you planed to work on unicode after 3.7?
