Subject: [OASIS Issue Tracker] Commented: (OFFICE-1895) RIGHTB and friendsis incompletely specified
[ http://tools.oasis-open.org/issues/browse/OFFICE-1895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15630#action_15630 ]
Eike Rathke commented on OFFICE-1895:
-------------------------------------
I still don't see how "RIGHTB is intended for use with languages that use the double-byte character set (DBCS)" could be related to UTF-8 (or any other Unicode encoding for that) an implementation uses as internal encoding.
Shouldn't this be more something like "recode the text from the internal encoding to DBCS (but which one?!? there is not a single DBCS encoding), bail out if the text is not representable in DBCS, otherwise let operate RIGHTB on that and return the resulting text converted back to the implementation's encoding"? Which still doesn't answer what should happen if the number passed as 'number-bytes' was odd. Or should that be number of double bytes instead?

> 6.6.6 RIGHTB
> Summary: Return a selected number of text characters from the right, using byte position.
> This description fails to indicate what happens in the likely situation that the selected bytes do not form a complete character sequence. Should that be an error or move to a correct position?
> Similarly for the otehr ...B functions
