Indeed. If you have output considerations then the number of Unicode codepoints isn't what you wanted anyway, you care about how many output glyphs there will be, that codepoint might result in zero glyphs, it might modify an adjacent glyph, or it might be best rendered as multiple glyphs.

If you're doing some sort of searching you want a normalization and probably pre-processing step, but again you won't care about trying to count Unicode code points.
