Description:
isCJKIVSCharacter needs to support CJK Unified Ideographs Extension Block C to
H for Unicode15
I'm curious about CJK Characters. (I'm Korean. But, I study & can speak both
Japanese and Mandarin Chinese a little bit.)
After I contribute to support Unicode 15's CJK Unified Ideographs Extension H
for GNOME characters, I checked CJK Unified Ideographs Extension Lists on
LibreOffice.
(GNOME characters commit link:
https://gitlab.gnome.org/GNOME/gnome-characters/-/commit/daef901e34d731d6d8fe8a1f966ea9f1f04e3a2f
)
However, It doesn't support CJK Unified Ideographs Extension Block C to H. Only
supports CJK Unified Ideographs and its Extension Block A, B.
In Unicode 15, the CJK Unified Ideographs Extension Block range is here
CJK Unified Ideographs: 4E00–9FFF
CJK Unified Ideographs Extension A: 3400–4DBF
CJK Unified Ideographs Extension B: 20000–2A6DF
CJK Unified Ideographs Extension C: 2A700–2B73F
CJK Unified Ideographs Extension D: 2B740–2B81F
CJK Unified Ideographs Extension E: 2B820–2CEAF
CJK Unified Ideographs Extension F: 2CEB0–2EBEF
CJK Unified Ideographs Extension G: 30000–3134F
CJK Unified Ideographs Extension H: 31350–323AF
Ref: https://www.unicode.org/versions/Unicode15.0.0/ch18.pdf
I installed the IPAmj Font Character Finder on LibreOffice
Link https://extensions.libreoffice.org/en/extensions/show/1077
Japanese MJ character Information table Ver.066.01.
https://moji.or.jp/mojikiban/mjlist/
https://moji.or.jp/mojikiban/font/
IPAmj Font Character Finder can look for characters in the CJK Unified
Ideographs Extension B or higher range.
such as "𫟘󠄂"(U+2B7D8) It's located in CJK Unified Ideographs Extension D.

So, For LibreOffice's CJK Users, We need to support CJK Unified Ideographs
Extension Block C to H for Unicode15
Steps to Reproduce:
1. Install the IPAmj Font Character Finder extensions on LibreOffice
Link https://extensions.libreoffice.org/en/extensions/show/1077
2. input the 'MJ060164' for MJcode or '2B7D8'UCS code
3. If the selected CJK font supports CJK Unified Ideographs Extension Block C
to H, It can show.
Actual Results:
If the selected CJK font supports CJK Unified Ideographs Extension Block C to
H, It can show.
Expected Results:
If the selected CJK font supports CJK Unified Ideographs Extension Block C to
H, It can show.
Reproducible: Always
