How to fix this error?

Find out the affected language
Execute report RSCPINST or RSCP0018 and check for any problems reported
there.
Check for the correct the language <-> code page mapping in table TCP0C
Sometimes a language is defined as logon language (profile parameter
zcsa/installed_languages) but the correct code page assignment is
missing in table TCP0C.
If you cannot find a problem in the I18n system configuration you can
call the function module "SCP_CODEPAGE_FOR_LANGUAGE" for all configured
languages (content of table TCP0I, record NAME = 'processed_languages',
ACTIVE = 'X') in transaction SE37. The exporting parameter CODEPAGE will
be empty for languages for which cannot be assigned a code page. Provide
the correct language-code page mapping for these languages.
