Can device name support multi-language

[Calvin]

Hi,

We have a device needs to support user change the device name. We already finished this function. The changed device name can be store in internal flash, and broadcast from next advertising. My question is: whether the device name can support multi-language. The user scenario as below,

1. User set their favorite name through Android or iOS App, the name may be in Chinese, Japanese, German,...or any other country language.
2. nRF51822 store the new name in the internal flash.
3. Next advertising, user can see their setting name on App correctly.

Please give me any your advice to achieve this function. Thanks for any coming information.

From the Bluetooth spec

12.1 DEVICE NAME CHARACTERISTIC
The Device Name characteristic shall contain the name of the device as an UTF-8 string ...

Since UTF8 encodes every unicode codepoint then you can have any and every language you like.

Well start by looking UTF8 up with google. Secondly you probably don't have to do anything, UTF8 is the most common encoding for strings - I see you've asked about iOS before, that's what iOS uses, that's what OSX uses, that's what Windows uses. So the string you get is most likely UTF8 anyway so you store it just like before and send it back just like before. There is nothing to do.
