Can something be done about the % sign being stripped off when posting code within code tags?

Sometimes it happens for me, sometimes it doesn't. This post from one of our moderators have tghe % stripped out for whatever reason.

I'm going to do a couple of tests here....

First test is typing in the code directly in the forum editor:
Code:
myBinary = %10101010
The second test is copy/paste from notepad
Code:
myBinary = %10101010
And the third and final test is copy/paste from MCSP
Code:
myBinary = %10101010
In all three cases the %-sign is visible when writing the post.

/Henrik.

EDIT: See, here it worked just fine in all three cases, yet in Dave post linked above the %-sign in stripped away.
