So, let's get this clear. Within an XML or HTML document, if I want an e
with a red acute accent on it, it is quite permissible to write:
e<span class="red-text">{U+0301}</span>
where {U+0301} is replaced by the actual Unicode character, and
"red-text" is defined in the stylesheet. So it is not a problem that
there is a defective combining sequence, nor that the accent is not
combined with the e as it would be in NFC. Is that correct?
If this is correct, then the Tamil problem which Peter J is concerned
about has gone away completely, or at least it is reduced to a tricky
rendering issue.
