As mentioned in "Assumption:", current grep expression can't catch
font files whose names are changed from upstream "Noto CJK fonts".
To avoid false negatives, use command of the form:
fc-list : file family variable
, where ":" works as a wildcard pattern.
Variable fonts can be detected by filtering the output with
"variable=True" and "Noto CJK" font-family variants.
