Reply To: Change font format with the GREP to change foreign language in document

Hi Jim, thanks for your advice. It works! But in this case I have to change the language format first before find the text then change to italic. Not automatically find text out of default language. So actually I want to change all the text using foreign language (Out of Default Language) change to italic format. Thanks
Btw, can InDesign detect foreign language? Usually, when we spell check, a red line will appear if the word or sentence does not use the default language. So actually, I want to change all the text with red line to be italic format.
