When I run
> hg import https://reviewboard-hg.mozilla.org/gecko/rev/1040f13fa3fcab02005c56d0befb78f173a8fb18

It fails with
> abort: decoding near 'io Cobos Álvarez <e': 'charmap' codec can't decode byte 0x81 in position 14: character maps to <undefined>!

This is because emilio's name contains a non-ASCII character "Á". (This is definitely not the first time I hit this :/)

Looking at Mercurial's code, it seems to be picking encoding with the following code:
> try:
>     encoding = environ.get("HGENCODING")
>     if not encoding:
>         encoding = locale.getpreferredencoding().encode('ascii') or 'ascii'
>         encoding = _encodingfixers.get(encoding, lambda: encoding)()
> except locale.Error:
>     encoding = 'ascii'

It's not completely clear to me what it means, but if I set HGENCODING to UTF-8, then the command can complete successfully.

I'm not sure whether it is something MozillaBuild should contain a fix for, or that Mercurial should fix for Windows.

Most power-users will likely want to use another editor, but now it will
be easier for new developers to get started.

Rather than falling back to the Windows system encoding, use UTF-8.
This provides benefits such as allowing accents in author names.
