Thanks for the replies!
The problem however isn't solved...
Having obtained the current byte index using col("."), I can't simply add n
to/subtract n from the return value of col(".") to find the beginning of
the next/previous multi-byte character (the -1 offset is ok because there's
a base bias).
I could use col(".") repeatedly but I would have to move the cursor
("normal l" or "normal h") beforehand.
Also, I could write a function that would analyze the UTF-8 header bits
("11110", "1110", "110", or "10") to determine the required position, but I
was hoping that there's another (easier) way to accomplish this.
Is there any function that lets me determine the byte position of the
beginning of the next/previous multi-byte character? I've seen none in the
docs...
