[issue25849] files, opened in unicode (text): write() returns symbols count, but seek() expect offset in bytes

[Марк Коренберг]

Марк Коренберг added the comment:

Well,  03e61104f7a2 adds good description, why not to enforce checks instead of saying that some values are unsupported ?

Also, idea in returning special object instance from tell(), this object should incapsulate byte offset. And allow for the seek() either such objects or zero.
