 The programmer might intend this behavior; in that case, the "alarm" should be acknowledged.

If that is what you want, then why not simply say:
     const unsigned char ch = 210;
Or change it to the char to a short (or int, long, etc).
?
It's a good and helpful warning.  I cannot see why you'd want to ignore it.
Do you expect to remember that 1234 really equals 210 in five years time?
