I'm not sure the IsRange function work easily, if at all, for this.
The easiest way is to create a panes view with an expression column, where the expression provides a means for you to see which track names contain chars within and without the Latin characters.
Create a new column, set the type to expression, and add the expression:
if(Regex([Name], /#[^ -~]#/), Contains non-ASCII, ASCII-only)
Then, in the pane view, you can select either value to see the two classes of track names, those with non-ASCII and those with ASCII-only. This works by having the regular expression search the collated range of SPACE to TILDE, which in ASCII is all printable characters (and space) which I think is what you're looking for. If not, the pattern can be modified easily enough to suit your needs.
