Steps to reproduce:

1. Open a PowerPoint presentation.
2. In a text box, insert text which includes wide characters, such as "Hello💻world".
3. Use the arrow keys to navigate the text. Notice that "💻w" is reported as a single character.

Actual behavior:

cap   H
right arrow
e
right arrow
l
right arrow
l
right arrow
o
right arrow
💻w
right arrow
o (caret is actually to the left of 'w')
right arrow
r (caret is actually to the left of 'o')
right arrow
l (caret is actually to the left of 'r')
right arrow
d (caret is actually to the left of 'l')
right arrow
blank (caret is actually to the left of 'd')
right arrow
blank (caret is actually to the right of 'd')

Expected behavior:

NVDA should report '💻' and 'w' separately, and should accurately report the position of the caret, even after wide characters.
