Need Grep To Add Single White Space Between English and Chinese Character

Thanks for everyone's replies! I've tried the suggestions, but it's still not doing what I intended. I now see there are some more conditions that I should have included in the original post. When I first applied my Character style to just the English characters, I did so using the following Character set:

[\da-zA-Z~2~d~r]

This sniffed out each English character and applied my character style. It did this on a character by character basis. In doing so, it skipped any white space between these words.

Now I need to describe a location that resides between an English and Chinese character and add a single white space.

Well, so you can base your search on English/non-English character change, or use already applied Char style. Let’s try the second approach. In 2 steps:

Find what:

(?<!.).

Change to:

$0

Find Format: point to your *English* char style here.

This will insert a space before EN text.

Then:

Find what:

.(?!.)

Change to:

$0

Find Format: point to your *English* char style.

This will insert a space after EN text.

Notice there must be a space character inserted before $0 in the first step, and after $0 in the second. That’s essential!

Both searches should be run only once. Every other run will keep inserting additional spaces.

SUMMARY

Find what: "([a-z,A-Z, ]+)"

Change to: " $1 "

Note: Do not include the " character in the Find/Change fields

FIND BLOCKS OF ENGLISH

This GREP expression should find simple blocks of English composed of just letters and spaces (there are many ways to do this kind of search.).

[a-z,A-Z, ]+

The square brackets identify a range of characters to be searched for. In this case we are looking for all the lower case letters, all the upper case letters and any spaces. The "+" character repeats the expression "one or more times".

If there are other characters you wanted included in your search you could just add them inside the square brackets. The following example now includes the "-" character in the search.

[a-z,A-Z, ,-]+

FIND AND REPLACE BLOCKS OF ENGLISH

To be able to reference everything that is found put the expression inside brackets.

([a-z,A-Z, ]+)

With the brackets included in the "Find what:" field, we can now refer to that result in the "Change to:" field by using "$1". To add a space at either end of the block of English simply add a space before and after the "$1" in the "Change to:" field.
