How to mix Latin and Chinese script with style?
If I understand your question correctly, you're asking how to format a mixed Chinese-Latin sentence... I don't think there is a set of rules on this...

The way I think of it is:

Use the punctuation appropriate for that given sentence/word...

我明天要跟我女朋友去看"Les Misérables"电影。 (It's a latin movie title, so use latin quotes... but a Chinese sentence, so use Chinese 句号)
