Well, the first two, U+0058 LATIN CAPITAL LETTER X and U+2169 ROMAN
NUMERAL TEN, are meant to be semantically distinct.

However, U+00FC LATIN SMALL LETTER U WITH DIAERESIS is supposed to be
semantically identical to U+0075 LATIN SMALL LETTER U plus U+0308
COMBINING DIAERESIS. In the first case, we're talking about different
abstract characters represented with different codepoints. In the
second case, we're talking about the same abstract character. Other
than a byte comparison, there is no distinction between both ü. You
wouldn't expect a font supporting Unicode to represent U+00FC
different that U+0075 plus U+0308.
