Yes, if lldb.exe crashes or otherwise exits without returning to main, then the codepage will stay set in the current console. The latter can be fixed with a static object destructor, but not the former. I don't think this would be a practical problem, since very few console applications depend on the codepage in the first place (those that do tend to set it manually when they start). The setting isn't permanent, either, it's only for the current console window until it closes (or is reset by somebody else). And it doesn't affect the bytes input/output by any programs, only the way the console interprets those bytes. I'd say the impact of changing the codepage without changing it back is very low.
That part of the patch is not quite as important -- without it UTF-8 I/O is broken, but it's already broken anyway unless the user has taken explicit steps to reconfigure Window's console system to support Unicode character display (which requires fiddling in the registry and rebooting). No one I know has done this. I can remove it from the patch if you think it's too risky.
We're using both liblldb and lldb.exe, though mostly liblldb. No Python bindings as of now.
The patch for LLVM has been accepted, I'm waiting for someone to commit it when they have a moment. I'll rebase this one on the tip again afterwards.
