Grep expression to change font style of Armenian characters only

Question

So I have several Armenian documents that I'm working with that have interspersed English portions which show up with missing fonts. Is there an expression that will change only the English portions to a different Character Style?

Joel is better versed in this, but it sounds like a combination of using the world-ready composer and having a reight to left language applied.

So Reuben, are you using the Middle East edition of InDesign? If so, there are tools to control whether the addresses and phone numbers render right-to-left or left-to-right.

If you're not using the Middle East edition, then I am starting to believe that there is a bug introduced in a recent version of ID where people using non-Latin scripts are experiencing RTL behavior being turned on "under the hood" when they have no tools in the interface to turn it off. But if you are using an ME edition of InDesign, you can do a Find/Change operation where you change all numbers and dashes and parentheses to Left-to-Right Direction and US English language, which should fix it for you.

Alireza's response is close, but it misses all capital letters. If you only needed A through Z and a through z, you could do something along these lines:

[a-z|A-Z]+

That's "one or more characters between a and z, or one or more characters between A and Z."

You say "English portions" in your post, but I couldn't tell you if that included numerals, punctuation, and so on. The following GREP query finds everything in Latin script, as well as generic Latin script punctuation:

[\x{0021}-\x{0100}]+

The \x{####} marks a Unicode value. So you can look at Unicode tables (or the Type -> Glyphs menu within InDesign) and replace the #### with the hex values for the range you want to look for.

If you want to get everything in the Latin-script range, but e.g. you want to exclude the comma and the colon, you can specify multiple ranges by doing something like this

[\x{####}-\x{####}|\x{####}-\x{####}]+

The vertical pipe | is "or" in GREP, so you the above expression is "anything between ___ and ___, or anything between ____ and _____".
