Subject: [OASIS Issue Tracker] Commented: (OFFICE-2663) Public Comment: What is a 'character'? (ODF 1.2, Part 2)

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=19250#action_19250 ] 

Eike Rathke commented on OFFICE-2663:

I don't think the issue goes away under Unicode. The example of CODE(), as a code page dependent non-interoperable function, may be bad, but the issue still remains with the UNICODE(), LEFT(), MID(), RIGHT() and LEN() functions. There are 4 flavors of normalization defined in the Unicode Standard, NFC, NFD, NFKC, and NFKD, all of which may deliver different results, though practically probably NFC would be used. I think we don't want to impose normalization or decomposition on evaluators, nor do we want to define normalization for the  CONCATENATE() function and the infix operator "&".

The conclusion is that we can define a character in a position dependent context only as the Unicode code point scalar value.
How to express?
