Expand description

The back-end implementing `UniformSampler` for `char`.

Unless you are implementing `UniformSampler` for your own type, this type should not be used directly, use `Uniform` instead.

This differs from integer range sampling since the range `0xD800..=0xDFFF` are used for surrogate pairs in UCS and UTF-16, and consequently are not valid Unicode code points. We must therefore avoid sampling values in this range.
