IMO, this is a deficiency of PEPV2. Note I said deficiency and not bug. Remote can do both but editor only allows one or the other.

Part of this is due to the fact that the symbols are in different Unicode code point (F000) vs normal ASCII (0000). Microsoft .NET, what PEPv2 runs under, does not easily handle both. Inside the XCF file, the editor must indicate either Symbol or Text such that things can be displayed properly.

IIRC, codepoint is right name but could be wrong. Barry's the text expert!

Note that you can do whatever you like in ProntoScript via Page Script. Just set the Panel/Button Label as you see fit.
