Supported with some limitations:

Babelize uses ISO 639-1 codes with optional region tags:

When no region is specified, Babelize uses the most common variant.

RTL languages (Arabic, Hebrew) are fully supported. Text direction is preserved in output files and bidirectional text is handled correctly.

For supported languages, control the tone of translations:

Option	Use Case
`formal`	Business documents, official communications
`neutral`	General content (default)
`informal`	Social media, casual content
