Avoid fonts with incomplete coverage of MATHEMATICAL chars
* lisp/international/fontset.el (setup-default-fontset): Include both
ends of each sub-range in 'script-representative-chars' (bug#51495).
Some fonts include glyphs for MATHEMATICAL SCRIPT CAPITAL codepoints
(#x1D49C-#x1D4B5) but not for MATHEMATICAL SCRIPT SMALL codepoints
(#x1D4B6-#x1D4CF), see e.g. KpMath[1].
'script-representative-chars' must thus include both CAPITAL and SMALL
codepoints to ensure that we filter those fonts out.
Bug#51495; discussed in help-gnu-emacs[2].
