Question

I’ve run into a strange problem. I have a string with a value containing ‘AA’.
I’m trying to find IndexOf the first accouring A. When I ask if the string Contains(“A”) it returns true. When using IndexOf(“A”) I keeps getting the default value -1! (se the picture below)

So far i tested there is only a problem with ‘A‘ and ‘a‘.
When putting 3 a‘s in the string I get the index of number 3, as if the first two doesn’t exsist.

When adding an extra a to the string, I get the default value -1 again.

I don’t know what is causing this, I have a suspision that it’s somehow connected to some langauge setting. I’m from denmark, and the use of the letters aa is a synonym for å.

Have anyone else experinced a simular problem or have a suggestion how to avoid it?

Windows 7 Ultimate (English)

‘aa’ is handled as an entity if the culture is da-DK. The question is sort of a duplicate, see String StartsWith() issue with Danish text.
