Well, it's at least partly related to that discussion, IMHO - see below. . . > Xterm supports two modes: ISO-8859-1 and UTF-8.

UTF-8 mode should work, shouldn't it (as long as video unit can draw the line drawing characters using their UTF-8 codes, of course)? > The line in question enables the use of the vt100 alternate character > set.

This doesn't work for Russian. > As a short term solution a conversion table should be added from a > Cyrillic Dos code page to 1251+ACS. I don't think this is a reasonable solution. Why not to use translation capabilities provided by the WideString manager? Otherwise you'd need to implement translation tables for all the different pairs...
