Subject: [OT] Only insert dottedcircle if at the beginning of paragraph
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f2eb3fa9dca8d21fae20c9b9dddad3245df74a05;p=platform%2Fupstream%2FlibHarfBuzzSharp.git

[OT] Only insert dottedcircle if at the beginning of paragraph

If the first char in the run is a combining mark, but there is text
before the run, don't insert dottedcircle.
