Want to convert plugin into English written in Other language

Hi everybody mostly the developers. My friend has written the plugin its great to 5 plugin but its in other language i want it to convert that language or the display pop comes its in other language i want that in English. Its in beta version if anybody interested plz. I have to ask for the permission also from the developer still not yet taken. but i have requested him and soon i will get the reply mean time is that possible to convert that language to English

Yes, please ask. I need it urgently.

It is possible if the developer wrote the code so that the GUI text can be localized.

Tell the developer to look at the API’s LanguageHandler class.
