Yes, this is why I requested from the OP that he verifies *in the browser*, what the
browser thinks the character set of the page is.
That is because browsers are inconsistent in interpreting server-sent responses.  Some
browsers will strictly respect what the server sends as a "Content-type" header (which,
according to the RFCs, they should do), but some will not (IE various versions over the
years are particular offenders in that respect).

By asking this, I was trying not to confuse the matter even further.
If the OP had answered and mentioned anything else than Unicode UTF-8, then that would
have been the trigger to dig deeper as to why this was the case.

It is often easy, and often tempting, to just provide a "recipe" that sems to work and
solves the immediate problem.
Unfortunately, such recipes then have a tendency to break down when conditions change
slightly, such as one user using a slightly different version of browser e.g.
