Missing characters

[eriku]

I use the signs/letters "a with a circle", "a with two dots" and "o with two dots" in some (swedish) text.
After I moved my HTML and PHP pages into XAMPP, those signs does not work any more (they show up as small, empty squares).

php.ini: default_charset = "UTF-8"

What have I missed?
How can I check what character set really is in use?

Windows 7 SP1.
XAMPP 5.6.12

Maybe your original Swedish text has been stored as UTF-16. That would explain why the UTF-8 decoder can't make sense of the given character stream.

You are quite right, Alex - thank you!
