*Purpose:
|
|
* Test if character is alphabetic.
|
|
* Handles MBCS chars correctly.
|
|
*
|
|
* Note: Use test against 0x00FF instead of _ISLEADBYTE
|
|
* to ensure that we don't call SBCS routine with a two-byte

*Entry:

* unsigned int c = character to test
|
|
*
|
|
*Exit:

* Returns TRUE if c is alphabetic, else FALSE
