I'm not trying to change the design, nor am I trying to make case-by case
decisions, the original paper covered that.
I think these are questions worth asking, sure, at least for control
characters as, for an arbitrary non-cjk, non-emoji neither an information
nor a specification exist.
Note that however it's not straightforward
* There is no spec so it's handled manually
https://github.com/termux/wcwidth/blob/master/wcwidth.c#L497
* C1 control characters may be mapped differently on EBCDIC platforms
* Combining characters not preceded by a grapheme starter are in fact
rendered
* We already ignore non leading codepoints in graphemes
* Negative width would be novel
I do not intend to explore these further but I'd be happy to review such
work :)
However, the original paper intended for CJK characters and emojis to be
covered, Unicode 14 and 15 added a number of such characters, I considered
this a bug.
But mostly, I consider specifying anything Unicode related in terms of
partially-assigned ranges to be a bug reminiscent of the identifiers of old.
Now, I expect SG16 will deal with this issue, but all the information is in
the issue.
The only design-ish question is whether we want to grandfather U+3248
CIRCLED NUMBER TEN ON BLACK SQUARE..U+324F CIRCLED NUMBER EIGHTY ON BLACK
SQUARE
for backward compat reasons.
Codepoints which would go from 1 to 2
