Alistair, are you aware of the following (article/codebase) ? https://medium.com/concerning-pharo/an-implementation-of-unicode-normalizat… Due to the size of the full DB it is doubtful it would become a standard part of Pharo though.

ZnUnicodeComposingReadStream?

by Alistair Grant

Hi Sven & Everyone, I need to convert an UTF8 encoded decomposed stream (Mac OS file names) in to a composed string, e.g.: string: 'test-Ã¤Ã¶Ã¼-aÌoÌuÌ' code points: #(116 101 115 116 45 228 246 252 45 97 776 111 776 117 776) utf8 encoding: #[116 101 115 116 45 195 164 195 182 195 188 45 97 204 136 111 204 136 117 204 136] In the above string, the first group of 3 accented characters are the same as the second group of 3, but are encoded differently - code points (228 246 252) vs (97 776 111 776 117 776). Reading the utf8 encoded stream should result in: string: 'test-Ã¤Ã¶Ã¼-Ã¤Ã¶Ã¼' code points: #(116 101 115 116 45 228 246 252 45 228 246 252) utf8 encoding: #[116 101 115 116 45 195 164 195 182 195 188 45 195 164 195 182 195 188] My current thought is to write a ZnUnicodeComposingReadStream which would wrap a ZnCharacterReadStream and return the composed characters. What do you think? Thanks! Alistair
