This is due ?\x21B5 is not a valid char,
so blank-mode uses the other vector:

   [?$ ?\n]

Which specifies ?$ as a visual mark.

Try this command in your system:

   M-: (format "%c" ?\x21B5) RET

Because ?\x24 == ?$ (valid char).

That is, both vectors have the same values.

Because ?\x21 == ?! (valid char).

Because ?\xB5 == µ (valid char).
