ANSI control characters not treated as zero width #24
Description
Hey folks!
According to the README.md, control characters should be treated as zero width, but it seems like ANSI color sequences are not currently. Code like the following (using strip_ansi_escapes) will fail for strings containing ANSI control characters:
fn assert_width(s: String) {
let stripped_width = std::str::from_utf8(&strip_ansi_escapes::strip(s.as_bytes()).unwrap())
.unwrap()
.width() as u16;
let unicode_width = s.width() as u16;
assert_eq!(
stripped_width, unicode_width,
"Mismatched width ({} vs {}) for `{:?}`",
stripped_width, unicode_width, s
);
}...such as:
"\u{1b}[1m========\u{1b}[0m"Is this expected?
