My remark may be pointless pedantry, but it could be the core of your
problem.
What you get is not a sequence of codepoints ('Unicode scalar
values' in the range 0 to 0x10ffff), but a sequence of glyph
'indices' (I just think of them as glyph numbers) in the range 0 to
0xffff. Although in some fonts, all glyphs have corresponding Unicode
characters (many in the PUA), this is by no means true of all fonts.
