Common mistakes
The user expects full URL encoding rather than Punycode
Fix: Use URL Encoder for URLs and query values. Punycode is mainly for internationalized domain labels.
The input is already Punycode
Fix: Use Punycode to Text if the value already starts with xn--.
The user expects full-domain normalization automatically
Fix: Review whether you are converting one label or a full hostname.
The input contains spaces or non-domain text
Fix: Punycode is most useful for domain labels and Unicode hostnames.
The user expects encryption or obfuscation
Fix: Punycode is just a representation format, not security.
