Supported Language IO languages in Salesforce
Language support for different Salesforce applications
Language IO supports 155 languages for Machine Translation (see the full list in the section below). However, support for these languages within Salesforce may vary depending on the application you use.
Salesforce Case, Salesforce Chat and Salesforce Enhanced Chat
To support a language for SF Case, SF Chat and SF Enhanced Chat, Language IO simply needs to add it to your configuration, even if it is not supported by Salesforce natively. To request new languages, submit a support request.
Salesforce Article
If you use SF Article, the list of supported languages must match the list of languages supported by the Salesforce Knowledge Base. This means that Language IO cannot configure your app with additional languages if they are not supported by Salesforce in the first place.
If you need to translate into a language that is not supported by your Salesforce app, you can still leverage Language IO's MT translation using the Language IO Secure Page Translator for Chrome.
