EXAMPLE

The $box-chars is typically platform dependent, it's setting is determined by the characters available in character set of the hosting platform. MS-DOS and Microsoft Windows environments might use a string such as:

"\xB3\xDA\xBF\xC0\xD9\xC2\xC3\xC5\xB4\xC1\xC4" 

X-Windows environments might use a string such as:

"\x19\x0D\x0C\x0E\x0B\x18\x15\x0F\x16\x17\x12" 

Both utilize platform specific characters.
