Cumulocity’s administration app offers the option to provide your own translations for certain texts. The process for doing so is described in the documentation.
This user interface only allows to add further translations for already supported languages. At the time of writing this, the supported languages are: German, English, English (US), Spanish, French, Japanese, Korean, Dutch, Polish, Portuguese, Chinese and Chinese (Taiwan)
In case you would like to add support for a whole new language, you can also do so by utilizing the Advanced branding tab of the Branding feature.
By adding the follwoing attribute to your JSON structure:
"languages": {
"de_CH": {
"name": "German (CH)",
"nativeName": "Deutsch (Schweiz)"
}
}
You could add for example swiss german to the supported languages.
After saving this change and applying this branding globally, you should be able to find the newly added language in the language settings and also in the localization user interface.
From there you can then go ahead and translate existing texts into your newly added language.
