Maybe we are not using the same vocabulary. The datatype char is not
able to hold values like '€' or '…' and a lot more of them.

A unicode symbol could consist of several bytes - example is '€'.
BString routines and e.g. STDOUT stream routines are (still) not able to
handle such metachar (int32) values as a symbol. They either will
handle such values as integers or truncate them to their last byte.
Thus for the moment only a BString return value would do.

I am not knowing, on what you are talking about. Where in the BeBook
e.g. things could be found documented which you are addressing here?
