This fixes an annoying issue in the shell's quoting algorithm (used for xtrace (set -x), printf %q, and other things) for UTF-8 locales, that caused it to encode perfectly printable UTF-8 characters unnecessarily and inconsistently. For example: $ (set -x; : 'aeu aéu') + : $'aeu a\u[e9]u' $ (set -x; : 'aéu aeu') + : 'aéu aeu' $ (set -x; : '正常終了 aeu') + : '正常終了 aeu' $ (set -x; : 'aeu 正常終了') + : $'aeu \u[6b63]\u[5e38]\u[7d42]\u[4e86]' This issue was originally reported by lijo george in May 2017: https://www.mail-archive.com/ast-developers@lists.research.att.com/msg01958.html src/cmd/ksh93/sh/string.c: - Add is_invisible() function that returns true if a character is a Unicode invisible (non-graph) character, excluding ASCII space. Ref.: https://unicode.org/charts/PDF/U2000.pdf - Use a fallback in is_invisible() if we cannot use the system's iswprint(3); this is the case for the ksh C.UTF-8 locale if the OS doesn't support that. Fall back to a hardcoded blacklist of invisible and control characters and put up with not encoding nonexistent characters into \u[xxxx] escapes. Ref.: https://unicode.org/charts/PDF/U2000.pdf - When deciding whether to switch to $'...' quoting mode (state=2), use is_invisible() instead of testing for ASCII 0-127 range. - In $'...' quoting mode, use is_invisible() to decide whether to encode wide characters into \u[xxxx] escapes. src/cmd/ksh93/tests/builtins.sh: - Add regression tests for shellquoting Arabic, Japanese and Latin UTF-8 characters, to be run only in a UTF-8 locale. The Arabic sample text[*] contains a couple of direction markers that are expected to be encoded into \u[xxxx] escapes. [*] source: https://r12a.github.io/scripts/tutorial/summaries/arabic
