Supported languages

Line 21 has extensive support for 119 unique languages.

We use UTF-8 encoding for all languages and a font family with excellent unicode coverage (Inter). This means that, technically, all languages are supported. However, the list of actually supported languages may be limited by availability of relevant services:

• human captioning: not covering many languages
• ASR engines: they tend to cover a lot of languages, but not all dialects or accents
• translation engines: good coverage, but here you should check if the pair source / target is supported
• RTMP encoding: the most limited subset of languages (see RTMP streaming)
• HLS streaming: all covered
• browser and overlay: all covered
• text destinations: in general, all covered, but you should check with the platform's documentation for more details and definitely test before the event
