No, Under Linux GCC, the source files saved as UTF-8 *with* BOM too. It's
works fine when it's Windows either Linux.
So, That make sure my application is cross-platform.

For now, the code will works fine with Qt4 either Qt5, under Windows or
Linux.

The current question is: Shall we need or no-need to use UTF-8 encoding as
default?
I thought we should use UTF-8 as default, Because it's the better way for
cross-platform.
What do you think?
Has anyone working for this?
