How does temporary files and File::Temp interact with Unicode and encodings?

In Perl, when working with temporary files using the File::Temp module, understanding the interaction with Unicode and encodings is crucial. The File::Temp module allows you to create temporary files safely and conveniently, but you must ensure that the data written to and read from these files is handled with the appropriate encoding to prevent issues with Unicode data.

When creating a temporary file, you can specify the output encoding to ensure that Unicode characters are correctly handled. This is particularly important when dealing with text that may contain characters outside the standard ASCII range.

The binmode function can be used to set the correct encoding for filehandles, ensuring that Perl treats the data as UTF-8 (or another desired encoding) when writing to and reading from the temporary file.
