in thread Japanese character in Linux

I guess, we'll have to go step by step. First, add "use Encode;". After you've obtained the values from DB, check if they are converted to internal perl encoding using

print Encode::is_utf8($sInstrumentNameJ), "\n";
If this produces "1", then the value is converted to perl's internal form and we should check how you output it to the terminal. If this produces empty string, then the value is not converted by the driver. In this case you have to convert it manually.

In either case, we have to know which locale is active in your terminal emulator. Normally, it shall be some UTF-8 locale, but who knows. Please provide output of "locale" command.

Also, if the "is_utf8" function produces empty string, it would be good to provide here the hexdump of the value you get from the database. Using this way for example

print unpack("H*", $sInstrumentNameJ), "\n";
And also the Japanese text it should correspond to.

    is_urt8 is returning nothing and output of unpack is 81698a94816a8bc9976d.
    
    We tried one more function find_encoding of Encode module and output is Encode::XS=SCALAR(0xaad27d0).
    
    W are not getting actual output when we use encode and decode fucntins.
    
    Output of locale command is as below
    LANG=C
    
    LC_CTYPE="C"
    
    LC_NUMERIC="C"
    
    LC_TIME="C"
    
    LC_COLLATE="C"
    
    LC_MONETARY="C"
    
    LC_MESSAGES="C"
    
    LC_PAPER="C"
    
    LC_NAME="C"
    
    LC_ADDRESS="C"
    
    LC_TELEPHONE="C"
    
    LC_MEASUREMENT="C"
    
    LC_IDENTIFICATION="C"
    
    LC_ALL=
    
    Please sugegst where we are going wrong.
    
    Thanx,

      There are quite a few things that are wrong. First of all, with locale "C" it is not possible to see any Japanese text, or actually any text outside of ASCII. So, it looks like you have to change your locale first. Assuming, that you use xterm as your terminal emulator, try to start it this way

      LC_CTYPE="en_US.UTF-8" xterm &
      Then check the output of locale command in that new terminal window. It should produce something like
      LANG= LC_CTYPE=en_US.UTF-8

      After that, you should convert your text to UTF-8 encoding. Since you haven't provided Japanese text corresponding to the hexdump, and since the hexdump looks like UTF-16, I'll assume, that it is UTF-16. Then you should output the variable using the following:

      Encode::from_to($your_variable, "UTF-16", "UTF-8"); print $your_variable, "\n";
      If this does not produce the result, then you may have some wrong font for terminal emulator :)

      Actually, sending the variable to terminal probably is not the most important thing. You have to work with that value inside of perl. Depending on what you want to do, you have to convert your variables back and forth. For example, to do pattern matching on it, you should first do

      use utf8; my $converted = Encode::decode("UTF-16", $your_variable); $converted =~ /some Japanese text/;

        Japanese charctares are ijɗm

        (株)極洋 Hex Dump is 81698a94816a8bc9976d. We are doing sybase to oracle migration PROJECT> We successfully migraed the data to Oracle using Characterset16 in Sql loader file. Now we are finding issue when application is inserting data from Perl. We are not concrened about displaying the Japanese data in console . We want the Japanese data to be able to handle by perl post migration. Please advise. Thanks Praful
