OK, it works after quite some hassles with font configuration.
Problems:

• There is no documentation on font configuration. It should be made clear 
(in the man page) that fontconfig is being used and how it can easily be 
supplied with favourite fonts (by linking a fonts folder to ~/.fonts).
• There is no mention of how fonts are addressed with -F. There should be 
some examples (in the man page) with related output of fc-list, to make clear 
the family name and style are to be used, not the full name or font file path 
name.
• If -F addresses a bitmap font, there may be a message like 'Cannot set font 
height' without any hint on what to do.
• If -F does not match any available font, there is no message at all, just 
some other default font is used (not the one used without -F, though).

Please enhance the handling of font setting.
