--parallel: Unicode output for status in ASCII mode

[The-Compiler]

In 43d65b1, an ASCII spinner was added if the output does not support unicode:

tox/src/tox/util/spinner.py

Lines 45 to 49 in 7a8a6ac

	self.frames = (
	self.UNICODE_FRAMES
	if _file_support_encoding(self.UNICODE_FRAMES, sys.stdout)
	else self.ASCII_FRAMES
	)

However, the final status outputs still contain unicode characters which might not be rendered properly (or even cause exceptions?):

tox/src/tox/util/spinner.py

Lines 107 to 114 in 7a8a6ac

	def succeed(self, key):
	self.finalize(key, "✔ OK", green=True)
	def fail(self, key):
	self.finalize(key, "✖ FAIL", red=True)
	def skip(self, key):
	self.finalize(key, "⚠ SKIP", white=True)

Not sure what an appropriate output would be - I guess no symbols at all, or maybe ":)", ":(" and ":|" similar to what happens without --parallel 😉
