Yes, clearly this would be for `master`.

I don't see why it would ever make sense.

Actually, I don't understand why

    (char-charset (unibyte-char-to-multibyte #x90))

should return `tis620-2533`, since the tis620.2533 standard defines
a coding-system similar to those of iso8859 and the corresponding chars
all exist in the BMP of Unicode (the "Thai block" U+0E01 through
U+0E7F), so I can't see any obvious reason why they should affect the
3x3fffxx private space used by Emacs for "eight-bit chars".
Could it be just a bug?
