struct TIsFixedWidthEncoding_Helper

Remarks

Metafunction which tests whether a given character type represents a fixed-width encoding.

We need to 'forward' the metafunction to a helper because of the C++ requirement that nested structs cannot be fully specialized. They can be partially specialized however, hence the helper function.
