I was just answering a question on SOF where I typed App_Code blah blah blah App_Code into the answer. Markdown interpreted the two underscores as beginning and ending some italicized text, and thus in the preview, it appeared like this: AppCode blah blah blah AppCode.
Is there some way to avoid this? Maybe a way to escape special markdown characters in cases like this? (I had to resort to using the _ html entity to get my question to appear properly, but that is kind of annoying)
