lldb on linux translates keypresses into unicode escapes

Hi

I compiled lldb (relase_40) on linux (ubuntu zesty). It runs, but it has this strange behaviour that keypresses are echoed as unicode escapes, but aren't really processed:

Typing "help" here:

./bin/lldb
(lldb) \U+4168\U+4165\U+416C\U+4170
error: empty command
(lldb)

As anyone seen this before and has an idea how to fix this ?

Ciao
