Available in

JSSupported

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

PYSee workaround

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
^[\p{L}\p{N}]+(?:-[\p{L}\p{N}]+)*$   (flags: u)

Raw source: ^[\p{L}\p{N}]+(?:-[\p{L}\p{N}]+)*$

How it works

[\p{L}\p{N}]+ matches one or more Unicode letters or numbers (so `café` and `東京` are valid). (?:-[\p{L}\p{N}]+)* allows additional hyphen-separated segments. The u flag is REQUIRED in JavaScript for \p{} property escapes; Python's stdlib `re` doesn't support \p{} (use \w with Unicode flag, or the `regex` package); Go RE2 has its own \p{...} support.
