Hi Tommy,

That's a neat idea! I didn't think of this at all.

Text is rendered by the gtk default rendering code, which appears to handle 
unicode glyphs just fine. I have just copy-pasted the paperclip glyph above in 
a register in gnucash 2.6.19 (!) and it is rendered correctly.

The only reservation I'd have is we don't control the user's default/preferred 
system font. If the chosen font doesn't have the chosen glyphs, the field 
would display a "glyph-not-found" character. I have no idea what glyphs the 
default fonts on the various platforms we support provide. That would need 
some experimentation first.
