# 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, use the `SourceCharSet` property. For example:

    objFilter.SourceCharSet=sourceCharSet;

To specify the target character set, instantiate the Filter object using the constructor `Filter(String outputCharSet, UInt32 filterFlags)`. For example:

    objFilter = new Filter(outputCharSet, filterFlags);
