Steven Rowe commented on LUCENE-2745:
-------------------------------------
bq. the only trick to deprecating this ArabicLetterTokenizer is the persian
case, since i dont think UAX#29 will split on zero-width-non-joiner, so we need
to do something to handle that case, otherwise we can default to a better
tokenizer here.
Robert, can you provide more detail? AFAICT from [this Wikipedia
article|http://en.wikipedia.org/wiki/Zero-width_non-joiner], ZWNJs are used in
Persian as display hints, not as word separators.
