For example, the bold tag isn't applied correctly. The following code should have the word 吃饭 in bold
but instead it shows 吃饭 in italic with asterisks around the word. like this: 我要*吃饭*啦
If there is a space before and after the bold tag, then it works. The preview section when you enter the question also works correctly. This wouldn't be a problem for English which most of the SE sites are based in, but it would be a problem for East Asian language based sites.
