For example, the bold tag isn't applied correctly. The following code should have the word 吃饭 in bold
我要**吃饭**啦
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.
