Emmanuel Lecharny updated DIRSERVER-805:
----------------------------------------

    Fix Version/s: pre-2.0

Not sure that it worth the effort right now... Chars above 0xFFFF are generaly 
attributed to dead langages like ougaritic, old persean, etc ...

> Supporting Unicode chars above 0xFFFF

> The current implementation and handling of LdapStrings does not support 
> characttres which are above unicode 0xFFFF. Even if Strings are translated to 
> UTF-8 before being transfered to the server, we still convert them back to 
> String inside the server. Some of those UTF-8 bytes may be encoded into 2 
> chars (if the UTF-8 bytes sequence contains 4 to 6 bytes), but all the 
> manipulations of those Stri,g does not take into account such characters.
> For instance, the DN parsing is based on single chars, and surrogates are not 
> handled at all.
> Even if not really important, because extended chars are not very common, 
> this is something that should be fixed in 2.0
