Sometimes large documents that have been translated into other languages will still have English written in them (company names, brand names, stuff that original creator wants to remain in English). Many times the English text will use a specific font, but that font does not support other alphabets/characters that appear in other languages, so the unsupported text comes up as red boxes.

There is no feature in InDesign that allows you to correctly identify the foreign language (all the red boxes) and lets you pick a different font WITHOUT changing the font for English. The only way to do this as of present is to manually highlight the red boxes line by line and pick a different font for that language, but if you have a 100 page document, this is painstakingly slow.

Dear Adobe, for Desktop Publishers everywhere please consider this, it would save us countless hours of our lives.
