Example
A letter with a diacritic may be represented with the letter, and a combining modifier letter. You normally think of é as one character, but it's really 2 code points:
U+0065— LATIN SMALL LETTER EU+0301— COMBINING ACUTE ACCENT
Similarly ç = c + ¸, and å = a + ˚
combined forms
To complicate matters, there is often a code point for the composed form as well:
"Café" = 'C' + 'a' + 'f' + 'e' + '´'
"Café" = 'C' + 'a' + 'f' + 'é'
Although these strings look the same, they are not equal, and they don't even have the same length (5 and 4 respectively).
