Title:
Incorrect JSON serialization of supplementary plane code points
Status in Zorba - The XQuery Processor:
Fix Committed
Bug description:
this bug is a follow-up of bug #1024448
Currently, the result of the following JSONiq query:
let $message := "👊"
return { "message": $message }
is serialized into incorrect JSON:
{ "message" : "\ufff0\uff9f\uff91\uff8a" }
the correct result would be:
{ "message" : "\ud83d\udc4a" }
Explanation:
Characters from the supplementory plane are usually represented in
utf-16 surrogate pairs within JSON results. The above result is in
particular incorrect because JSON allows only 4 hex digits after '\u'.
utf-16 surrogate pairs alway fit into a 4 hex digit or 2 x 4 hex digit
window which is most probably the reason why utf-16 is used.
This has been greatly fixed in the JSON parser by Paul (see mp:
https://code.launchpad.net/~paul-lucas/zorba/bug-1024448/+merge/115248
), but it still needs to be fixed in the serializer.
@Paul: I'm not sure if you are the right person to assign this bug to?
thanks
