Hi,
bash manpage says for printf contains the following statement:
if the leading character is a single or double quote, the value is
the ASCII value of the following character.
POSIX uses a different wording:
If the leading character is a single-quote or double-quote, the value
shall be the numeric value in the underlying codeset of the character
following the single-quote or double-quote.
Bash says that ASCII will always be used, POSIX says that the conversion
is codeset-dependent.
Bash code seems to agree with POSIX and contradict its manpage:
$ printf -v b "\xc3\xbf\xbe"
$ printf "$b" | { while LC_ALL=C read -N1 c; do \
LC_ALL=C printf "%d %q\n" "'$c" "$c"; done; }
195 $'\303'
191 $'\277'
190 $'\276'
$ printf "$b" | { while LC_ALL=C read -N1 c; do \
LC_ALL=C.UTF-8 printf "%d %q\n" "'$c" "$c"; done; }
195 $'\303'
255 $'\277'
190 $'\276'
Should the manpage be changed? Or the code modified to always use ASCII
as the reference codeset?
