large title bars fix ?

hi there

I am trying the CTWM - on OpenSUSE, it is the v4.0.3
what I noticed is there is no way to have UTF locale , en_GB.UTF-8 in my case
as this produces large title bars, very annoying indeed

so ,if I may ask is there any solution or it is just "beating a dead
horse" as the CTWM is based on the outdated TWM .

I know I would use en_GB as locale, but this will break filenames that
are stored in unicode,

thanks !
