It is a very rare art to misunderstand my words that extreme.

BString s += '€';

is an example for such a char parameter, which is not capable for UTF8 symbols.

I made a simple proposal for a BString method SymbolAt(), which might need
about 20 lines of code. The discussion about it raised a lot of opposition by
people, whose arguments I cannot understand, because they are completely
misleading.

I decide to invest my programming time in more fruitful projects instead. 

Sorry, if I should have waisted your time.
