My understanding is this: ZWNJ and ZWJ are artificial constructs in Unicode to give hints about rendering of conjuncts (i.e., they don't change the spelling etc of word they appear in). The intended difference between them is a bit of a mystery to me. For indic languages, they have the following paradigm: C1 + hasanta + ZWNJ + C2 prevents the conjunction of C1+C2 C1 + hasanta + ZWJ + C2 renders C1+C2 as half-C1 C2 The second case is very relevant to Devanagari, but not at all relevant (in my opinion, and other people have a different opinion on this) to Bengali. An example of the first is ঠন্ঠনে as opposed to ঠন্ঠনে (Note that Sayamindu has recently fixed some pango bugs without which you may not see things correctly. There are some screenshots at http://bengalionline.net/rendering-bugs/rendering-bugs.html). Even though the standard use of ZWJ is rare in Bengali, it has been used in non-standard ways in the past to "fix" design bugs in Unicode. Initially it was used to encode khanda ta, and now that that design bug has been fixed, it's being used to encode ra-japhala (to distinguish it from ja-reph). Sayamindu has a link on this earlier in this thread. Hope that helps. -Deepayan ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
