Glpk does not support unicode as was noticed by Xypron. However, you can
use some cyrillic encoding like koi-8 or windows-1251. Note also that such
string literals should be enclosed within quotes, e.g.

set S := "cyrillic text", "another abracadabra", ... ;

Another way is to use multibyte characters; but in this case you need to
have a specialized text editor.
