The resolution was taken at the Beijing meeting of WG2.

(I told the committee this would happen.)
The tail fragment was part of three rather old IBM code tables which
were all mapped into those nasty presentation forms, and this
particular glyph fragment was missing, and apparently this is causing
them problems for data conversion. That, I think, wouldn't be the
case for you, even if the character was used in a national character
set. It's easier to map a logical character set one-to-many and
many-to-one. The presentation-based model breaks because they're
taking fragments and sticking them together.

I'm just saying what is LIKELY to be the reaction to such a proposal.
Now, if you consider it a lot more like the peseta or rupee currency
symbols, and showed a glyph that really didn't look like a word,
maybe. Can you do a discussion document with scans of price tags,
printed samples, and so on, showing its unity and narrowness?

Mmm.
