In the Android user agent HTTP header, what does “U” mean?

Question

I am trying to implement an HTTP user agent agent header parser.

I'm curious to know the value of “U” in the header of the HTTP HTTP Agent for Android.

This is an example Android Android Agent Agent Header:

Mozilla / 5.0 (Linux; U ; Android 4.0.2; ko-kr; Galaxy Nexus Build / ICL53F) AppleWebKit / 534.30 (KHTML, e.g. Gecko) Version /4.0 Mobile Safari / 534.30

Does anyone know about this?
