lldb converts keystrokes to unicode literals

I have a fresh copy of lldb. If I enter the following in the gnome terminal:

$ lldb
(lldb)
error: empty command
(lldb) test <- "test" are keystrokes, they are not displayed

The letters "test" are converted to

(lldb) \U+21174\U+21165\U+21173\U+21174

The pattern is different each time I launch lldb and the terminal. It happens right after lldb makes its first output, but may also happen at the first input. Sometimes keys such as enter and backspace are converted into unicode literals too.

Another thing I noticed is that although the unicode literals are often invalid, they follow a specific pattern. If a is represented by \U+E2061, then b must be represented by \U+E2062. I am not sure why does this happen.

I also noticed that this does not happen with gdb: (fresh installation)

(gdb) test

(gdb) aaa <- Not converted to unicode literals

I do have some modifications in my .bashrc but turning off these modifications does not make the problem go away.

Edit: Just tested that the problem also occurs under console mode (<C-A-F3> for gnome) and other emulators (termite).

Copy-pasted contents are converted to unicode literals as well.

Re: lldb converts keystrokes to unicode literals

It's a know bug, might be on the LLVM (upstream) side:
