WideUpperCase or How to uppercase the filename
In this chapter we will learn how to achieve goals similar to the Case rule.
First, we will uppercase the filename and lowercase the extention. We will use WideUpperCase and WideLowerCase functions that take a string as a parameter and return that string in proper case.
FileName := WideUpperCase(WideExtractBaseName(FileName)) + WideLowerCase(WideExtractFileExt(FileName));
We can also capitalize every word with WideCaseCapitalize function:
FileName := WideCaseCapitalize(WideExtractBaseName(FileName)) + WideExtractFileExt(FileName);
or invert case with WideCaseInvert function:
FileName := WideCaseInvert(FileName);
Making only first letter capital is a bit more complex and will be described in the next chapter.
