This seems to have some side effects with ispell, save

---------------------
óptica
---------------------

to something.tex, make sure flyspell-large-region limit is set to 1, select
castellano8 dictionary and run flyspell-buffer

if: Bug: misspelled word `ptica' (output pos 7) not found in buffer

and contents of flyspell-region buffer (containing words ispell considers
misspelled) is

ptica

Seems that by doing that, ispell is also setting to the tex charset, e.g.

$ echo français | ispell -l -t -d francais
fran
ais

with the word "français" and the francais dict (they could also be used to test
this problem)

aspell seems to accept that.
