CGI character set display

[cah]

For some of my CGIs, I have to enter Chinese characters to them.
After migrating to RHEL 7, I started using UTF8 over Big5 due to the higher acceptance of UTF8. Also, Apache is sort of forcing to use UTF8 for uniform behavior.

Here is an example of entering Chinese character and Big5 shows garbage codes:

Entering:

Code: Select all

 For 蕭家緯(Chia-Wei Hsiao)
entering grade 一年級(1st Grade)

    $35.00

CCCA Annual Membership:

but got

Code: Select all

$15.00 CCCA Annual Membership: $20.00 Grand Total: $560.00 

The way to correct this is to change the code from

Code: Select all

print $cgi->header(-charset  => 'Big5');

to:

Code: Select all

print $cgi->header(-charset  => 'UTF8');

After making the change, the new output becomes readable:

Code: Select all

and data can be written to database (MySQL) then.
