Some characters do false-positively count as 2 while occupying 1 column in terminal

[erictheswift]

stringWidth('◼') // 2 in v7, 1 in v5
stringWidth('⚠') // 2 in v7, 1 in v5
stringWidth('✔') // 2 in v7, 1 in v5
(likely not complete list)

seems related to emoji-regex package updates

I guess it is not true that every character considered as emoji due to spec occupies double width. At least at current moment in time.

More test cases where this happens, emoji-regex seems indeed potentially buggy:

t.is(stringWidth('\u21a9'), 1);
t.is(stringWidth('\u2194'), 1);
t.is(stringWidth('\u2197'), 1);
t.is(stringWidth('✔'), 1);
t.is(stringWidth('\u2709'), 1);
t.is(stringWidth('\u26a0'), 1);

I get the same issue with ♥ for example. Until resolved, one can stick with version ^5.1.2.

I got the same issue with ♀ and ♂ in v7 and v6. I'm sticking with v5.1.2 too.
