Subject: Fix caret_count value when AAT is disabled
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ae44645d60fe8271ad18b004434d475eaeb7ad6;p=platform%2Fupstream%2FlibHarfBuzzSharp.git

Fix caret_count value when AAT is disabled

Set caret_count to zero as that is what we want to happen inside lcar when
there is no result.
