I can't seem to be able to write some of the characters of the hungarian language into the code editor. The problematic chars are:
ő (o with two paralel lines above it)
ű (u with two paralel lines above it)
When I press the specific key, the char simply does not get inserted. Other applications, including text editors can accept these chars.

"Courier" (non TTF bitmap font) is missing cyrillic characters (you can check this by "Character map" in Win Accessories/System tools).
To enter cyrillic characters, you have to set the right code-page for your file (U++ stores codepage of package and file in package information).
Current codepage is displayed in the window caption. Default codepage is windows-1252, but that does not allow cyrillic chars. Please check that.
You can set code-page in Package organizer or File properties.

I have set 'koi8-r' everywhere in file properties, package organizer and setup for environment. Still can't type cyrillic.
Output of 'locale' is the following:
LANG=ru_RU.KOI8-R
LC_CTYPE="ru_RU.KOI8-R"
LC_COLLATE="ru_RU.KOI8-R"
LC_TIME="ru_RU.KOI8-R"
LC_NUMERIC="ru_RU.KOI8-R"
LC_MONETARY="ru_RU.KOI8-R"
LC_MESSAGES="ru_RU.KOI8-R"
LC_ALL=
One more thing. ide falls to core when I try to set encoding in package organizer to two or more packages simultanuosly without pressing OK button.

Ahh, sorry, as you were speaking about Courier, I came to conclusion you are speaking about Win32.
Well, I think that this is a bug (or rather unimplemented feature). So far, U++ was tested with (and developed for) UTF-8 linux systems.
You can check the code in CtrlCore/X11Proc.cpp around line 137.

Staring at the code
Status status;
int len = XmbLookupString(w.xic, &event->xkey, buff, sizeof(buff), &keysym, &status);
buff[len] = 0;
if(status == XLookupChars || status == XLookupBoth)
chr = FromUtf8(buff, len)[0];
I think that the problem is that instead of FromUtf8 (only) there should be general conversion based on current locale...

Umm.. guys..
Please help a newcomer 
I'm trying to write my labels in Russian, but to no avail.
In .lay-designer everything seems just fine, since I've reinstalled everything and set codepage to Win-1251 since the very start. Yes, I've tried to simply change the codepage before, but my problem remained, hence -> the reinstallation.
Okay, I can type in Russian and see the text on my controls, fine. But as soon as I start my app, the text is in gibberish, that is European chars from the second part of (8-bit ) ASCII table are used.
It looks like my application is using a wrong (i.e. w/o Cyrillic chars) font. You see, when I create a form in MS Visual Studio (2003), the font selection dialog looks like this -
http://img211.imageshack.us/my.php?image=fontselcrwd2.png
As you can see, it allows you to select encoding for your font, which is great. The IDE's font selection panel doesn't offer this.
Could someone please explain, how to use Cyrillic characters on controls?
P.S. I'm on WinXP SP1, English, but Russian fonts/keyboard layout are installed, no problem with that whatsoever, Russian filenames are ok, everything works.

There are two encoding settings that get into the action when you develop your app:
First, there is encoding used to edit the file. However, for the app running, text is just a sequence of bytes; it needs to know how to interpret it.
U++ is basically Unicode/UTF-8 system (most of internal processing ends as unicode). Anyway, as in the real life things are never as simple (e.g. we have to maintain legacy apps in Win-1250  , you can set the "default charset" and most string literals are then converted from it (somewhere in DrawText).
Long story short, please try
SetDefaultCharset(CHARSET_WIN1251)
I guess you will also need set the language, so you can do both using
SetLanguage(LNGC_('R', 'U', 'R', 'U', CHARSET_WIN1251));
BTW, maybe even better is to stay with utf-8, which is "default default encoding", as long as you are not concerned with "external" troubles.
