Problems displaying UTF-8 coded cyrillic characters in terminal mode

Problems displaying UTF-8 coded cyrillic characters in terminal mode

[Kamen TOMOV]

Hello,

I'm having problems opening UTF-8 coded files containing text in
cyrillic in terminal mode. The text appears as '?'. Any other coding
is displayed properly (CP1251, ISO-8859-5, KOI8-R). The problem exists
only in terminal mode, e.g. if I start emacs in X mode, everything is
OK. I'm using GNU Emacs 21.3.1. Any help would be appreciated.

Thanks,

Emacs 21.3 by default does not convert UTF-8 Cyrillic text to
ISO-8859-5 internally. On X, it uses Unicode fonts to display UTF-8
text, and Cyrillic fonts to display the other encodings. In terminal
mode, you only have one terminal encoding, so that is the reason why
you cannot see the UTF-8 text.

See the functions unify-8859-on-encoding-mode and
unify-8859-on-decoding-mode to turn on conversion between UTF-8 and
ISO-8859-5.

Thanks for that. I tried these functions by putting them in .emacs but
I didn't see much difference. I solved the problem by making the
terminal UTF-8 aware and now emacs can display text in different
encodings including UTF-8.
