*Purpose:
|

* Test if the supplied character is punctuation or not.
|
|
* Handles MBCS characters 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 an punctuation character; else FALSE
