Opt Subject: PRI #340: Inconsistent bidi classes

Bidi classes are inconsistent between similar characters. For example, U+3373 SQUARE AU 
is L and U+32CE SQUARE EV is ON. They are both Latin-letter unit symbols fit into 
ideographic squares, so there is no bidi-relevant difference between them and they 
should have the same bidi class.

The list of inconsistencies:

• parenthesized Hangul: U+3200..321C vs. U+321D..321E
• circled Hangul: U+3260..327B vs. U+327C..327E
• Latin letters in ideographic squares: U+3250, U+32CC..32CF, U+3377..337A, U+33DE..33DF, 
	U+33FF vs. U+3371..3376, U+3380..33DD, U+1F190
• ancient Greek symbols: U+10140..1018C vs. U+1018D..1018E

Opt Subject: UAX #9 (PRI #340) Suggestion

In Section 5.1 of PU-UAX #9 for Unicode 10.0, please correct the text to
indicate that *both* a C and a Java reference implementation are available.

Also, the mention of the bidi demo utility in the same paragraph should be (at
least) moved into a separate paragraph and strongly hedged, because the
current demo utility is stuck at UBA 6.2, with no immediate prospects for
update, and also does not handle supplemental characters correctly. Mention
here in the text of UAX #9 should include the appropriate warnings, *before*
people click through and find problems with the utility and discover that it
is seriously down-level and non-conformant.
