Documentation/filesystems/vfat.txt: fix a remark that implies UCS2

All non-historic operating systems support the full range of Unicode here,
thus you can make filenames for example in Gothic (πŒΌπŒ΄π‰π…), the other Gothic
(π“‚β„―β„΄π“Œ) or the third Gothic (π—†π–Ύπ—ˆπ—), or declare something as πŸ’©.

Characters above U+FFFF are encoded on four bytes.
