There is no straightforward way to know if a string is lower, upper or title case. A workaround such as Contains function or REGEX ones has to be used.
The creation of the following functions would make it easier :
- IsTitleCase(String) : tests if a string is in TitleCase
- IsUpperCase(String) : tests if a string is in UpperCase
- IsLowerCase(String) : tests if a string is in LowerCase
They would all return a boolean and be in the Test category.
