Removing the symbol restrictions will allow Emacs to pick (incorrect)
ISO8859-1 fonts for these characters again.  Have you changed
something in the C code to prevent that?

Looking at the DejaVu Sans Mono glyphs in "gucharmap", it appears that
#x2200 is the problem.  The #x201C, #x2200, #x2500 combination was an
attempt to find "representative" symbol codepoints, but that
combination isn't all-or-nothing.  Can you first try leaving just
#x201C in `script-representative-chars'?  That's LEFT DOUBLE QUOTATION
MARK, so it should have wide coverage.
