Application Caret Position granularity

[kpozin]

This page doesn't specify the granularity of Application Caret Positions. When you increment the ACP by one, by what unit have you moved through the text stream? Is it:

• 1 UTF-16 code unit
• 1 Unicode code point
• 1 grapheme cluster
• something else

?
