bug#23754: Guile doesn't show correct character while interpreting script file

[Ws Hu]

Hi,

guile replaces non-ascii unicodes with question marks while interpreting script file:

$ cat test.scm
(display "蛤")
$ file test.scm
test.scm: UTF-8 Unicode text
$ guile test.scm
?

 

while it works fine in REPL mode:

$ guile <<<'(display "蛤")'

Enter `,help' for help.
蛤

 

and I think it's not a problem of my locale configuration:

$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL= 

because my terminal recognizes utf8 bytes:

$ printf "\xe8\x9b\xa4"
蛤

where e8-9b-a4 is the utf8-encoded Chinese character "蛤"
