[Pkg-zsh-devel] Bug#659932: zsh: printf %<n>s in UTF-8 is not always POSIX-compliant

[Vincent Lefevre]

Package: zsh
Version: 4.3.15-1
Severity: normal

In UTF-8 locales:

xvii% printf ".%2s.\n" é
. é.
xvii% emulate sh
xvii% printf ".%2s.\n" é
.é.
xvii% emulate ksh       
xvii% printf ".%2s.\n" é
. é.

It is correct in sh mode (according to POSIX[*]), but not in ksh mode,
which should also follow the POSIX behavior. What about zsh mode?

for %<n>s.
