Hi,

I'm planning constantly moving my apps to FPC 3.0.0. Compiled the smallest app and everything seems to working fine. In official recent changes list I read that main different is in unicode / utf8 / codepage. What does it mean? Is there any simple real example with "what you did in FPC 2.6.4 and can't do in 3.0.0"? Does it mean that String type has in FPC 3.0.0 different behavior?

Regards

The official changes page for FPC 3.0 states what exactly has changed, what you should avoid doing in your code and also literally "This new feature generally works transparently":
