So effectively, Unicode/ISO 10646 lacks a precomposed character to support
capital H with line (or macron?) below used in ISO 233 and ISO 233-2. They
have been forgotten when ISO 1646 was created...
What is the status of ISO 233 and ISO 233-2? Given the publication dates
they may be more accurate than DIN 31635 and ISO/R 233 used by
"orientalists". So who is supposed to use the two other standards?
And for round-trip compatibility, there's no solution for now, unless
Unicode adds either the encoding of a compatibility character (unlikely I
suppose, given the current policy), or at least a "named sequence", to
suggest that fonts should be designed to include this single letter
Given the Anglo-American usage (which may be coded with the double diacritic
U+035F coded between k and h), I think that there may even exist variants
with a joining breve below [or above] both kh letters (the double diacritic
U+035C [or U+0361] encoded between k and h), notably in texts where
underlining may be confusive with other usages, and where not noting the
cluster may also be confusive. As these uses are academic, any of those
notations may be introduced when precision is needed (after all the Latin
alphabet is foreign to the Arabic script, and using Latin is just a way to
discuss of Arabic system in European languages, so this is just a notation
for easier understanding, like is the IPA notation system, not something for
general linguisitic use).
