Document valid values of the char type As discussed at #93392, the current documentation on what constitutes a valid char isn't very detailed and is partly on the MAX constant rather than the type itself. This PR expands on that information, stating the actual numerical range, giving examples of what won't work, and also mentions how a `char` might be a valid USV but still not be a defined character (terminology checked against [Unicode 14.0, table 2-3](https://www.unicode.org/versions/Unicode14.0.0/ch02.pdf#M9.61673.TableTitle.Table.22.Types.of.Code.Points)). |
