Because Japanese doesn't have spaces, I've noticed a lot of posters have had trouble bolding individual words in sentences (myself included). See this answer for an example: Passive-transitive-verb vs. Intransitive-verb （他動詞の受け身 vs. 自動詞) (not to pick on istrasci).
One of the issues is that the bolding appears correct in the preview pane, but not in the actual post. For example,
学生は**日本語**を教わった appears as 学生は日本語を教わった in the preview pane but 学生は*日本語*を教わった in the actual post.
Is this a bug with the preview panel that should be fixed, or should we develop a workaround as a community?
