Lucifers,
Currently, Lucy uses CharBuf in two ways. One is to build Strings which is the
typical use case. In two places they're used as a resizable buffer to hold
UTF-8 data.

In TextTermStepper:

I'm wondering whether we should restrict CharBuf to string building and rename
it to something like StringBuilder. This would allow to remove a couple of
methods. For resizable buffers, users could switch to ByteBuf, maybe with
additional convenience methods to get Strings in and out of ByteBufs.
