Description
Holds a character value and provides a number of utility functions to manipulate it and test its properties. For example, functions to convert the character to uppercase and test whether it’s a control character.
The character value is stored as a 32-bit unsigned integer. The shorthand “TChar value” is used to describe the character value wrapped by a TChar object.
TChar can be used to represent Unicode values outside plane 0 (that is, the extended Unicode range from 0x10000 to 0xFFFFF). This differentiates it from TText which can only be used for 16-bit Unicode character values.
这用法不对,编译过不去啊,, function call '[TBuf8<220>].Insert(int, {lval} unsigned char)' does not match 原型void Insert(TInt aPos,const TDesC8& aDes); 'TDes8::Insert(int, const TDesC8 &)' (non-static)
