I use Chinese characters in many of my references and would like for only the roman characters to be italized in the title and not the characters. So, instead of this:
You would probably need to divide the title into two fields, one for the Latin characters and one for the Chinese characters, and then edit the output style accordingly.
I thought that if you did the formatting in the field of the record it would override the style’s formatting, but testing that, didn’t seem to work.
In which case, I would edit the Reference Type to create a field for the Chinese portion, move that to the new field (or you could use another field already there, that you don’t use for any other purpose) and adjust your style sheet to include this new field in the appropriate placement (with the appropriate “link adjacent text” for the spaces and, “forced separation” so the extra spaces don’t show when there isn’t a Chinese part of the title). If you can’t get it to work quite right, post the style here, and one of the user group can tweak it for you.
If this is a rare occurence, I would just fix it before submitting though. The publisher is probably pretty adept at correcting these minor formating problems in the proofing stages too.
