Unicode strageness with lldb

[Pete French]

Using the lldb installed with 11-STABLE from an hour or so ago. Thoigh
I dont know when this started, as I have been using db until now.

First command I type is fine, subsequent commands, every keypress I
type looks like this:

(lldb) \U+7F68\U+7F65\U+7F08

That's an attempted 'bt' so something is adding 0x7F00 to it somewhere.

Anyone else seeing this ? Its in a standard xterm, options '-sb +lc -en utf8'
but I have tried with other options and it does the same thing.
