BCP 47 Parser

IETF BCP 47 language tags are strings used to specify the language of text content or language preferences in various contexts.

The tags are built from subtags separated by hyphens. By combining multiple subtags, you can identify a specific language, script, region, variant, and more.

This tool parses BCP 47 strings and allows you to view, inspect, and debug their components.
