What means
It supplies one bend in a character-based drawing.
Sharp MZ text graphics used fixed screen cells; each circle segment occupied one cell, and neighboring pieces continued the curve through the grid.
The European MZ-80K character set included this glyph by 1978.
Why is byte 9D different from U+1CC31?
They belong to two different character encodings.
In the 1982 MZ-700 European primary display table, display byte 9D and Unicode U+1CC31 identify the same glyph in different systems.
When converting old MZ text, use the character map for its original set; byte 9D alone is not a Unicode value.
