Is it possible to restrict a smart filter to a certain unicode range?

I would like to use this in a smart filter in addition to a few other restrictions.

Create a compound rule (hold down the Option key and press the [•••] button). Inside the All compound, add two Custom rules that check the lower and upper limit of the Unicode block:

In the filter rules, write Unicode values as decimal numbers (e.g. 97 for a or 122 for z) prefix a number with 0x to write the Unicode value with hexadecimal digits (e.g. 0x61 for a or 0x7A for z).


Thanks, that worked perfectly.
