One q. of lexicography, one q. of orthography

(1) I would also appreciate any information you might have (perhaps
even a link to a website) on misc. lingual symbols used in
lexicography --not phonetics, but misc. such as the obelus, the use of
the "degree" symbol to indicate the repetition of a preciously stated
root, standard symbols for derivation, etc. --my problem being that
none of the dictionaries I actually have make use of any such symbols
in a standardized or consistent way. Ideally I would also like to know
the Latin/Greek names for these symbols, as (e.g., obelus) this is the
only way to find the Unicode entity corresponding thereunto.


(2) I would appreciate any information you might have on the special
Burmese ".d.dhu" glyph (viz., retroflex "d" + retroflex aspirate "dh"
+ "u" forming one peculiar glyph) --in my Burmese edition of Kacc,
this is drawn as if the latter glyph were miniaturized and then
inserted within the former (with u below, but no subscript consonant
whatsoever).  What I *DO NOT KNOW* is whether this is more a matter of
vernacular or classical orthography --or if it is an acceptable
variant for both.
