# Set the Character Set During Filtering

You can convert the character set of a file at the time the file is filtered.

To specify the source character set of a file, after calling fpInit() or fpInitWithLicenseData(), call fpSetSrcCharSet(), and set the `eCharSet` argument to any value in the enumerated list in `KVCharSet` in `kvcharset.h`.

To determine the final output character set, call the `fpGetTrgCharSet()` function after filtering is complete.

To specify the target character set, set the `outputCharSet` argument of fpInit() or fpInitWithLicenseData() to any value in the enumerated list in `KVCharSet` in `kvcharset.h`.

Not all values of the enumerated list can be used as a target character set. Coded Character Sets lists character sets that can be used as output.
