[3.0] UTF8 and IFS

[Stephane Chazelas]

It seems that multi-byte characters can't be used as splitting ones:

bash-3.00$ locale charmap
UTF-8
bash-3.00$ a=$(printf '%b' 'A\0303\0251B')
bash-3.00$ IFS=$(printf '%b' '\0303\0251')
bash-3.00$ [[ $a = "A${IFS}B" ]] && echo yes
yes
bash-3.00$ set $a
bash-3.00$ [[ $1 = A ]] || echo no
no
bash-3.00$ printf %s "$1" | od -to1
0000000 101 303 251 102
0000004

Problem also for "$*":
bash-3.00$ set a b
bash-3.00$ printf %s "$*" | od -to1
0000000 141 303 142
0000003

(instead of 141 303 251 142)

regards,
Stephane
