The hyphenation patterns in the `ruhyphen' bundle are in koi8
encoding, and koi8 can't be used by groff because it uses characters
in the range 0x80-0xA0 which are not supported by groff.

groff_diff is right.  Thanks for mentioning it; I've just fixed it in
the CVS.

Well, the default bundle of groff doesn't come with koi8 support.

Hmm, I've just looked up the definition of koi8-r, and it should be
possible to use the subrange 0xA1-0xFF, which covers the Cyrillic
characters.

Where's the problem?

Currently not.

Hehe.  OK, will try to remember.
