Hello,
I need to break a string down into individual characters.
In English that's pretty easy.
But in some languages what a user perceives as a single block is
actually a base character plus accents plus vowel markers plus tone
markers plus...
eg: เก
is made of
U+0E40 ( เ ) thai character sara e
U+0E01 ( ก ) thai character ko kai
To help with this NSString has the methods:
rangeOfComposedCharacterSequencesForRange:
rangeOfComposedCharacterSequenceAtIndex:
and CFString has:
CFStringGetRangeOfComposedCharactersAtIndex.
but then some languages - like german, will sometimes combine certain
blocks together
so SS becomes ß
the document http://unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries
seems to have some good information about this,
so I'm not completely lost as to how to proceed. But this strikes me
as one of those problems that other people have struck many times
before,
any suggestions would be deeply appreciated.
thank you
