Forwarding to freebsd-hackers@/[email protected] The question remain open and I need help. tr -C is implemented by FreeBSD tr -C but I can't find examples (or a testcase) where tr -c and tr -C differ.
Ced PS: Who wrote tr -C and how can I contact the author? ---------- Forwarded message ---------- From: Cedric Blancher <[email protected]> Date: 5 April 2013 16:04 Subject: Where does FreeBSD tr -C differ from tr -c? To: [email protected] Has anyone discovered examples for FreeBSD tr -c producing different output than tr -C? I tried this (ksh93) test script but it NEVER produces a difference in the en_US.utf8 and fr_FR.utf-8 locales: ------ snip ------ builtin rm typeset string typeset -li16 n_ch ; for (( n_ch=1 ; n_ch < 0x5000 ; n_ch++ )) ; do ch="$(printf "\u[${n_ch/~(El)16#/}]")" string+="$ch" done typeset -li16 m1 m2 for (( m1=0x32 ; m1 < 0x3000 ; m1+=7 )) ; do (( m2=m1+1500 )) range="$(printf "\u[${m1/~(El)16#/}]-\u[${m2/~(El)16#/}]")" tr -Cd "$range" <<<"$string" >'res_C' & tr -cd "$range" <<<"$string" >'res_c' & wait res_c="$( <'res_c' )" res_C="$( <'res_C' )" rm 'res_c' 'res_C' if [[ "$res_c" != "$res_C" ]] ; then printf 'DIFFER range=%q\n' "${range}" fi done exit 0 ------ snip ------ So when does tr -C differ from tr -c? I need examples, please...
