Describe the bug / provide steps to reproduce it

1. Create a new blank editor
2. Paste the following text:

a'b
a"b
a’b
a“b

3. Place the cursor at the end of line 1, and look at the line and column numbers displayed in the status bar.
4. Repeat for each line.

Expected result:

1:4
2:4
3:4
4:4

Actual result:

1:4
2:4
3:6
4:6

It looks like Zed is looking at the number of UTF-8 bytes in the line before the cursor, instead of the number of UTF-8 characters.
