How can I handle ?

[swankjesse]

This is a bug in OkHttp. We should never crash on unexpected data from the server.

+1 same here....

[pidoubleyou]

The same problem occurs if the request header contains Chinese or German characters like 'ä'

This has been probably fixed by 3ec5227.

Http2xStream.readHttp2HeadersList() was changed to call Headers.Builder.addLenient() and not Headers.Builder.add(), as seen in the stack trace.
