Subject: optimize column width calculation and utf-8 encode for ASCII
X-Git-Url: https://git.xinqibao.xyz/st.git/commitdiff_plain/cde480c6939e62771ba3b60ef4eb848031aee9f9?hp=cde480c6939e62771ba3b60ef4eb848031aee9f9

optimize column width calculation and utf-8 encode for ASCII

In particular on OpenBSD and on glibc wcwidth() is quite expensive.
On musl there is little difference.
