Patched as above

ReproducibleScript:
# The bug report that I submitted earlier today contains a questionable
patch.
# Pleas apply the attached one instead.

ObservedBehavior:
# The bad patch causes the G2 fonts to match various Unicode characters
# in the range 0x0100-0x0fff, incorrectly

DesiredBehavior:
# The symbol fonts should use the symbol encoding only for 8-bit
characters

Patch applied, although I don't have a G2 font to test the change.
The fix is applied for 8.3.0.
