Encoding issues using ADB to dispatch messages

Issue

I've implemented a service that listens to commands issued through ADB. An example of a command sent through ADB could look like this:

adb shell am startservice -a com.testandroid.SEND_SMS -e number 123123123 -e message "åäö"

Now, the problem here is that the encoding of the string "åäö" seems to mess up. If I take that string extras and immediately output it to the log, I get a square "[]", unknown character. If I send this message I get chinese characters in the messages app. As long as I stick to non-umlaut characters (ASCII I guess), everything works fine.

I'm using Windows 7 and the command line for this. I have not touched the encoding of the command line and I've tried to process the extras string by getting the byte characters, passing in UTF-8 as an encoding argument, then creating a new String passing in UTF-8 as an encoding argument there as well. No dice, though.

The values of the bytes, when using getBytes() are å: -27, ä: -92, ö: -74

How do I get this to play nice so I can make use of at least the umlauts?

All of this works perfectly fine in Linux.

Solution

Concluding, either the problem is situated in cmd.exe or adb.exe. Until either one or both are updated to be more compliant with eachother I will sadly not be able to make use of this for the time being.
