Umlauts crash client

[ahbnr]

Hi, I just tried to send some text to my phone and noticed that umlauts seem to crash the client:

$ mconnectctl share-text /org/mconnect/device/0 "äöüß"

** (mconnectctl:116036): CRITICAL **: 13:24:28.728: file ../src/mconnectctl/main.vala: line 79: unexpected error: Invalid byte sequence in conversion input (g_convert_error, 1)

I havent yet taken a look into the code, but I guess only a very limited encoding (ASCII?) is supported?
Of course I can work around this by not using umlauts, but I just wanted to report this.

EDIT: I just noticed this is probably related to this issue: #47
