If so we might need a new MangledWithLanguage class and use it only where we need it so it doesn't make lldb_private::Symbol and lldb_private::Function and lldb_private::Block's inlined info take up more space. We spent a lot of time doing memory analysis on LLDB and lldb_private::Symbol objects were consistently at the top of the heap.

1 - No - because, for example, Delphi use same mangling, but has thin differences in types name demangling and namespace separator (same with Java).

2 - We need to know exact language for given function or method name demangling with its parameters types on full header.
