Formally, yes.

However, most text editors I know (and all of those who explicitly support UTF-8) use the BOM as Heuristics to detect UTF-8 if configured to "auto-detect encoding" or similar settings.

Second, the abovementioned PEP-0263 specifies that Python will use the UTF-8 BOM as indication of UTF-8 encoded files if no explicit encoding definition is given (and throw an error if an UTF-8 BOM is present together with an encoding definition specifying a different encoding).

So for the given use case of Python source files, prepending an UTF-8 BOM is a working solution, although properly specifying the encoding definition clearly is the preferable solution (which I indicated using the word "better" in my original answer).

Best regards

Markus Schaber
