Subject: In POSIX mode, ${#var} measures length in bytes, not characters
Date: Sun, 07 Jun 2015 02:23:26 +0200 [thread overview]
Message-ID: <55738EFE.1050805@inlv.org> (raw)
When in 'emulate sh' mode, ${#var} substitutes the length of the
variable in bytes, not characters. This is contrary to the standard; the
length in characters is supposed to be substituted.[*]
Oddly enough, zsh is POSIX compliant here in native mode, but
non-compliant in POSIX mode.
Confirmed in zsh 4.3.11 (Mac OS X), 5.0.2 (Linux) and 5.0.8 (Mac OS X).
