Calling EncoderStringWriter::write successively does not equal EncoderStringWriter::write_all

The problem

From the docs it seems like using EncoderStringWriter::write incrementally and EncoderStringWriter::write_all once should produce the same result.

This is not the case as seen in the following example:

Hm, that doesn't seem great. Thanks for the report; I'll look into it.

The issue is that the third write() call isn't consuming all of the input, which is per the spec. It only consumes the first two bytes. If you call write() again with the remaining un-used input, all is well: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=a0770eb15be84f64778143d78e8b500a. I'll also add a test to ensure this works.
