Matt McCline commented on HIVE-20044:
-------------------------------------
[~teddy.choi] [~ewohlstadter] Second thoughts...
Do you need to write a variation of StringExpr.padRight that accounts for
Unicode? Do other any other parts of your Arrow SerDe need to consider Unicode
character length vs. byte length?
> Arrow Serde should pad char values and handle empty strings correctly

> When Arrow Serde serializes char values, it loses padding. Also when it
> counts empty strings, sometimes it makes a smaller number. It should pad char
> values and handle empty strings correctly.
