Description Vitaly Dyackhov 2023-02-03 08:18:44 PST

Several ways to check whether a character is a Unicode control character are used throughout the codebase. Such as:
```
u_charType(character) == U_CONTROL_CHAR
```
or
```
(character >= nullCharacter && character < space) || (character >= deleteCharacter && character < noBreakSpace)
```
We have a nice helper for this in `CharacterProperties.h` - `isControlCharacter()`.
It would be nice to use it since it is shorter and describes the intent better.
