Let's call the styles a tie. Using the SOWPODS scrabble wordlist (no
currency symbols, so False answer):
>>> unicode_currency = {chr(c) for c in range(0xFFFF) if
>>> unicodedata.category(chr(c)) == "Sc"}
>>> wordlist = open('/usr/local/share/sowpods').read()
>>> len(wordlist)
2707021
>>> %timeit any(unicodedata.category(ch) == "Sc" for ch in wordlist)
176 ms ± 1.75 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
>>> %timeit any(unicodedata.category(ch) == "Sc" for ch in set(wordlist))
17.8 ms ± 121 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> bool(set(wordlist) & unicode_currency)
False
>>> %timeit bool(set(wordlist) & unicode_currency)
18 ms ± 216 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
Of course, this is a small character set of 26 lowercase letters (and
newline as I did it). A more diverse alphabet might tip the timing
slightly, but it's going to be a small matter either way.

The dead increasingly dominate and strangle both the living and the
not-yet born. Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
