* A simple eight bit char string class.
|
|
* Used by decimal number formatting to hold the string form of numbers.
|
|
*
|
|
* For internal ICU use only. Not public API.
|
|
*
|
|
* TODO: ICU should have a light-weight general purpose (char *) string class
|
|
* available for internal use; this would eliminate the
|
|
* need for this class.
