Description

I'm trying to implement R bindings for the compute function "utf8_center" but in cases where there are an odd number of spaces in total, the extra space is added to the left.  However, in R, the extra space is added to the right.

Please can we have another string pad option to determine which side the extra space goes, so I can make the functionality match?
