Description

calculate the width of UTF-8 string s. if ambi_is_double is given, the ambiguous width character's width is 2, otherwise it's 1. fullwidth/doublewidth character's width is 2, and other character's width is 1. if default_width is given, it will be the width of unprintable character, used display a non-character mark for these characters. if s is a code point, return the width of this code point.

(number) = utf8.width(s,ambi_is_double,default_width)

Parameters

s: (string)
ambi_is_double: (boolean) optional
default_width: (number) optional

Return values

Returns (number) width
