String implements a set of methods such as lessThanOrEqual:collatingTable:. These methods do not work reliably for instances with DoubleByteString or QuadByteString, and are likely to encounter errors, and not sort according to a customized table.
Methods that rely on these, such as asciiLessThan:, etc. also may have issues.
These methods have been deprecated in v.3.2. With Unicode string sorting, this collation table sort is not longer needed.
