Background

When Mozilla’s IDN support was first being developed, the standard itself had not completely stabilized. As such, there were no domain registrars that offered IDN domains, and if one was to register a domain based on the then-current state of the standard, there was no guarantee it would work by the time the standard was finalized. The initial checkin for IDN support contained this preference, which affects conversions from UTF8 (Unicode) to ACE (punycode). The alteration simply appends a string to the end of the conversion, but this would allow developers to “catch” IDNs for testing.

This preference is largely for debugging purposes.

Convert Unicode to punycode normally. (Default)

Caveats

Unless you’re actually modifying or testing Mozilla’s IDN code, there’s no reason to set this preference to true. Doing so will break normal IDN functionality.
