It is, but that's irrelevant for the example. In the source


all characters are ASCII (i.e. all of "letter u", "single
quote", "backslash", "letter x", "letter b", "digit 5").
As a consequence, this source text has the same meaning in all
supported source encodings (as source encodings must be ASCII

The Unicode literal shown here does not get its interpretation
from Latin-1. Instead, it directly gets its interpretation from
the Unicode coded character set. The string is a short-hand


and this denotes character U+00B5 (just as u'\u20ac" denotes
U+20AC; the same holds for any other u'\uXXXX').
