[mule] xemacs doesn't recognize some symbols

[Andriy Gapon]

I am running xemacs-mule (21.4.19) in uk_UA.UTF-8 locale and I try to
enter some multi-lingual text using AltGr and Compose key. For some
symbols this works very well, but for others not.

E.g. I can enter symbols like
???
and many cyrillic symbols like
??????.

On the other hand I can not enter some other quite basic symbols, xemacs
messages follow:

leftdoublequotemark not defined.
rightdoublequotemark not defined.
endash not defined.
Sh-emdash not defined.
Ukrainian_ghe_with_upturn not defined.
Macedonia_gje not defined.

Where do these messages come from and what do they mean ?
Is this something wrong with the font I use ?
On the other hand, if open a document that already contains the
troublesome symbols they are rendered as they should be. It seems that
the problem is with input.

P.S. the input was done after C-x Ret f and selecting utf-8, default
input method is used.
