Related: fdo#50284 apple's modern symbol font is unicode encoded

So codepoints that are from the legacy range need to be converted to their
unicode equivalents even in the presence of an installed "symbol" font on
MacOSX.

This should work out ok if input codepoints that exist in the apple symbol
unicode are used, they should be left untouched by this conversion.
