Of course it must be supported. My point is that many strings (in my
applications, all but those strings that result from slurping in a
file or process output in one go -- example, not a statistically valid
sample!) are not the beginning of "what once was a stream". It is
error-prone (not to mention unaesthetic) to not make that distinction.

'Hallo'
Yes! Exactly (except in reverse, we want to _read_ from the slurped
stream-as-string, not write to one)! ... and there's no need for a
utf-8-sig codec for strings, since you can support the usage in
exactly this way.
