Detailed Description

Finds those signed char -> integer conversions which might indicate a / programming error.

The basic problem with the signed char, that it might store the non-ASCII characters as negative values. This behavior can cause a misunderstanding of the written code both when an explicit and when an implicit conversion happens.
