Preview Post messes up case-sensitive BB-codes

[SmurfAsH]

Letters in uppercase gets formated to lowercase so breaks the code.

Try to Preview a row like..
R + M + S + E + B + LB + XB + K + C


I'm using Mozilla FireFox 27.0.1

I think this happens in all browsers, but only when all characters are in uppercase.

So this example will "break" because all characters are converted to lowercase:

::R::R + ::M::M + ::S::S + ::E::E + ::B::B + ::LB::LB + ::A:: XB + ::K:: K + ::C::C

But this example will not:

Try ::R::R + ::M::M + ::S::S + ::E::E + ::B::B + ::LB::LB + ::A:: XB + ::K:: K + ::C::C

Not sure why the forum does this and will look into it, but wanted to describe the problem as specific as possible
