Sure, that's fine. We can limit symbol warnings to the symbols containing= =20 non-ASCII chars all of which are confusable with ASCII. This will warn ab= out=20 "=D1=81=D0=B0n" (with Cyrillic "=D1=81" and "=D0=B0") but not about "=D1=81= =D1=82=D0=B0=D0=BB=D0=B8=D0=BD" (with Cyrillic "a"). The point of the guideline is not to warn about every possible confusable= =20 character; it's to defend against malicious code.
