I don't see how the user can know this. Depending on the usage, an odd
glyph can look like a bullet or other marker. In some cases therefore,
the user might presume it is just a unique way of calling attention to
something rather than a missing character.
When I demonstrate problems with not setting charset in web pages
correctly, I use an example where because of charset mislabeling the
Euro symbol turns into a filled square box, turning a declared currency
into a value next to a box, where the user might then presume their
native currency aside a list bullet. Of course the meaning of the page
is therefore significantly changed.
