I noticed an apparent oddity concerning ten characters in the
Khmer block. These characters are U+17F0 to U+17F9
(ATTEK SON to ATTEK PRAMBUON). This oddity concerns
their Bidi Class. Most characters of General Category No
that are specific to a particular script have the same Bidi
Class as the regular letters and numbers of that script.
However, these characters have Bidi Class ON. The only
other characters of category No and class ON are the
vulgar fractions and the circled or parenthesized number
dingbats, which see use with all sorts of scripts. The Khmer
divination number symbols are likely to only be used with
the Khmer script.
So my question is, is this Bidi Class of these numbers correct?
Since their behavior when used with Khmer would be the same
as if they had been given Bidi Class L, if it is an error, it is
understandable how it could have escaped notice by the
users of this script. If it isn't an error, could someone please
explain why they are have class ON instead of class L?
