Because UTF-8 is multibyte and there is no char corresponding to your combination of \xe9 plus following space.

Why should it succeed in both utf-8 and latin-1?

Here how the same sentence should be in utf-8:

> > > o.decode('latin-1').encode("utf-8") 'a test of \xc3\xa9 char'

In Python 3, files are opened text (decoded to Unicode) for you; you don't need to tell BeautifulSoup what codec to decode from.

If decoding of the data fails, that's because you didn't tell the open() call what codec to use when reading the file; add the correct codec with an encoding argument:
