Linden Lab Issue ID: DEV-16209


 Description  « Hide
In LSO LSL, the entire Unicode range was supported by complying to RFC 2279 (about 2 billion possible characters).
Mono supports RFC 3629 which supplants RFC 2279 and limits the Unicode range to the first 1,114,112 character codes.

This directly effects these functions:
llBase64ToString
llUnescapeURL

Strings being passed from LSO scripts to Mono scripts will become corrupted (in a reliable way) if they contain characters outside the limited Unicode range.

While I don't really use anything beyond the old ASCII range of characters anyway, this is still not a good thing, especially when it comes to international character support etc.

It shouldn't really effect internationalization considering that RFC 3629 has been turned into an ISO standard. And to my knowledge accepted by Unicode.

This isn't something I think that should be fixed. This issue was created just to provide documentation of the change.

Agreed, this is good documentation and should be added to the wiki when we roll out Mono. Ultimately I'd like to see proper byte array support, so this kind of subversion of strings isn't needed.

Added Strife's observation to the wiki FAQ, so that we don't lose sight of it.
