Overline for pango text?

[Stefan Salewski <mail ssalewski de>]

Hello,

I have to draw some simple technical diagrams, I am using cairo (from
Ruby rcairo) with interactive GTK drawing-area and PNG, PDF export.
Currently I am using cairos toy text for text labels.

My intention was to using pango now, but there seems to be still no
support for overline/overbar (similar to existing underline), see

http://en.wikipedia.org/wiki/Overline

Will there come support for overline in pango soon, or what is the best
solution to fake it?

Best regards,

Stefan Salewski
