Symbols for Okinawan Sanshin

Dear all,

In this email I summarize my findings about symbols for sanshin, as
James Ingram and Razvan Beuran asked me to do.

First, I searched in some fonts whether some UTF-8 characters
representing sanshin notes existed or not.

NOTEHEADS
In sanshin, many symbols are noteheads (representing "do", "re", "mi",
"fa", etc.). These are the basic noteheads, all of them typical Japanese
characters included in UTF-8:
工 五 六 七 八 九
四 上 中 尺
合 乙 老

Then, for notes that are higher than those, they make a version with the
radical イ on the left:

仜 伍     仈 仇
伵 仩 仲 伬
佮 亿 佬

There is also a version with the radical ロ on the left:
叿 㕶   𠮟 叭 㕤
呬     呎
哈   咾

Please note that イ六 and イ七 are missing (I could not find them in the
table of the fonts and my Japanese friend also could't find them by
drawing in the IME).
In most of the resources I could find on the Internet, those two symbols
are not used for sanshin, but at least I found one place in which
drawings of these characters appear as a kind of alternatives to 仜 and 伍

About the ones with ロ I could only find those in the tables of the
japanese fonts, and from them only 㕶 and 呎 are used.
However, I know that in sanshin at least ロ上 ロ中 are used too, but I could
not find them in the tables.
It also happens that 叱 and 𠮟 exist, I am not sure which is the correct
one, but I think it is the second.

Please notice that most of the fonts cannot represent all the Unicode
characters of the Han (CJK) section, and therefore I cannot search them
well.

ACCIDENTALS
In general, accidentals such as flat (♭) and sharp (♯) are now
represented with the Western symbols. However, you can note that in the
lower part of the following image, they use the same kanjis surrounded
by a circle to represent the flat (♭) version of the notes. I don't know
whether these exist in the Unicode.

OTHER NOTATION:
In Okinawan music there are other symbols used to represent effects with
the voice, such as keeping a note for long time, glissando, accent, and
so on. I think these are the ones in which you won't find much in the
Unicode. I can send a couple of photocopies from books and research
papers in which they make a kind of inventory for such symbols.

Regards,
