Try GNU Libidn

This page allows you to try the string preparation, punycode encode/decode and ToASCII/ToUnicode operations of GNU Libidn. If you encounter a problem with this page, report a thorough analyse of it to bug-libidn@gnu.org.

If you are interested in commercial support of Libidn and/or proprietary customizations, you can contact me.

Free shrimp sandwiches are served over here.

This page ignores any Accept-Charset headers sent by your browser. Instead, the Unicode repertoire encoded as UTF-8 is used. If you are using software that cannot handle this, you must select another MIME charset below. BIG5, ISO-2022-JP-2, ISO-8859-1, and KOI-8 are popular choices. I am sorry for the inconvenience.
