How to use Convert Punycode to a String
- 1. Paste the Punycode label. Enter the Punycode-encoded text, such as an 'xn--' domain label, into the input pane exactly as it appears in the source.
- 2. Read the decoded Unicode string. The tool reverses the Punycode algorithm from RFC 3492 and shows the original Unicode string, restoring accented or non-Latin characters.
- 3. Copy the decoded text. Copy the recovered Unicode string and use it wherever the readable, internationalized version of the name is needed.
When to use Convert Punycode to a String
Convert Punycode to a String decodes a Punycode string back to its original Unicode form, reversing the ASCII-safe encoding used for internationalized domain names. Use it whenever you have the encoded label and need the human-readable name behind it.
- Reading an internationalized domain from a browser bar. A browser or email client shows a hostname starting with 'xn--' and you want to see the actual Unicode domain name a user would recognize, like 'münchen.de'.
- Investigating a suspicious link. A URL contains a Punycode-encoded hostname and you want to decode it to check whether it matches a legitimate brand name or is a lookalike domain.
- Debugging IDN handling in an application. Your code stores domain labels in their Punycode form internally, and you need to decode a stored value back to Unicode to confirm it round-trips correctly.
- Understanding a DNS zone file entry. A DNS zone file lists a Punycode-encoded label, and decoding it clarifies which internationalized name the record actually corresponds to.
