--- Comment #21 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Yes confirming issue now affects both Graphite and OT font use on Windows
alike.
Removing the easyHack as no code pointers. Have not checked if Linux builds are
likewise affected.

Version: 7.1.0.0.alpha0+ (x64)
Build ID: <buildversion>
CPU threads: 4; OS: Windows 10.0 Build 18363; UI render: Skia/Vulkan; VCL: win

Setting additional font feature (from Paragraph style or Character DF) is
sufficient to confuse the Special Character Dialog. On launching the dialog an
incorrect font populates the charmap, and any glyph selected is applied to
document in that incorrect font.

So, seems an issue in resolving font name with an appended smart font notation
(either Harfbuzz or Graphite handling).

@Tomaž -- is there a way to make use of your font/FeatureParser work on bug
58941 to at least pass a corrected/truncated font name to the charmap Special
Character dialog? Or, the much more ambitious effort to render (and pick from)
the charmap with the font feature(s) applied?
