Odp: RE: Why was L2/25-061 provisionally assigned?

[piotrunio-2004@wp.pl]

The way I see it is that U+02C8 and U+02CC are spacing versions of U+030D and U+0329 diacritics, and therefore to compose a spacing character with both diacritics, the spacing character of one and combining character of the other could be used. And there is already precedent of spacing diacritics composed with combining characters, particularly U+0385 which is composed as U+00A8 U+0301 (although the precomposed version is encoded as it's essential for CP869, CP1253, and ISO 8859-7 compatibility).

While the quoted passage on the Submitting Character Proposals page makes sense for “normal letter with diacritic” proposals, which were once commonplace, I don’t think it’s typical to attach combining marks to a modifier letter such as U+02C8 or U+02CC, or for UTC to recommend composition in such cases.   The NormalizationTest file does not include any instances of combining characters used with modifier letters, except for a few wacky, cross-script, stress-test cases involving a combination of Latin letters, Hebrew accents, and Adlam modifiers.   Perhaps someone has authoritative info on whether the difference in handling is policy or just the way it’s been.   --  Doug Ewell, CC, ALB | Lakewood, CO, US | ewellic.org
