In Bitstream Vera Sans Mono 8 in gvim 8.0.600 for GTK3 (which I just
made using "make reconfig" after an update of the python2, python3 and
IIRC lua packages), U+20F0 is present in the buffer and gvim
recognises it as a composing character, but its display is easy to
miss: AFAICT only 3 pixels are in the foreground colour, at top right
of the character cell, in this shape (shown here by one asterisk per
pixel):
**
*
When the cursor is on it, ga and g8 give the expected values below the
status line.
Best regards,
Tony.
