In Go version 1.7.3, the unicode package provides 2 maps: FoldCategory and FoldScript. FoldCategory is only supposed to map category names to tables of code points, but includes script names ("Common", "Greek", "Inherited"). By contrast, although FoldScript is supposed to map script names to tables of code points, the 3 script names ("Common", "Greek", "Inherited") are missing and FoldScript is an empty map.

This bug could be fixed by instead defining Fold Category and FoldScript thus:

var FoldCategory = map[string]*RangeTable{ "L": foldL, "Ll": foldLl, "Lt": foldLt, "Lu": foldLu, "M": foldM, "Mn": foldMn, }

var FoldScript = map[string]*RangeTable{ "Common": foldCommon, "Greek": foldGreek, "Inherited": foldInherited, }

This much better fits what the user of unicode expects when reading the descriptions of FoldCategory and FoldScript (as well as better matching what the names of the variables imply).
