ideally I'd like to break the string in to:
the smallest possible segments which do not need to horizontally
overlap when displayed in order to make sense to a reader.
so the composed character sequence:
g̈
U+0067 ( g ) latin small letter g
U+0308 ( ̈ ) combining diaeresis
would need to be one substring because the glyphs overlap horizontally
rangeOfComposedCharacterSequenceAtIndex sees this as one composed
character. Just like you require.
the composed character sequence in Thai:
เก
(adj. mischievous)
U+0E40 ( เ ) thai character sara e
U+0E01 ( ก ) thai character ko kai
would ideally be broken into two substrings
rangeOfComposedCharacterSequenceAtIndex sees this as two composed
characters.
ฺีBut why do you call it a composed character sequence? It is just
a vowel + consonant.
but:
กึ
would have to be one substring
rangeOfComposedCharacterSequenceAtIndex sees this as one composed
character.
In Thai you can get composed character sequences that look a bit like
เกอะ
I do not think that this is a composed character. "เถอะ" which
looks similar (but is a real word) is broken into 4 chars (just as you
want it) by rangeOfComposedCharacterSequenceAtIndex.
At the moment i'm using rangeOfComposedCharacterSequenceAtIndex.
And if a sequence is too wide for my tile I scale it down.
Do you have an example where the result of
rangeOfComposedCharacterSequenceAtIndex is too wide?
Kind regards,
Gerriet.
