set
Sets the Chromium language, which is used on the default error pages and message dialogs.
By default, the language is dynamically configured according to the default locale of the application. If the list of supported languages does not contain the language obtained from the application locale, then the US English language is used. The current option allows you to override the default behavior and configure the Chromium engine with the given language.
Setting of this property has the same effect as adding --lang switch.
