Ah yes, that will probably work. That's what I meant with:

"It seems there's some fixes in 5.6 which will let me use
Font.styleName to match a font by style name, which would be a
workaround [1]. But right now I'm stuck with 5.4.1."

Completely understandable if you missed that, sorry for sending such a
tirade of e-mails!
