Detailed Description

Safe natural base 64 alphabet, both without ASCII code-point sorting order.

Order is considered a natural extension of decimal symbols, i.e. 0 < a < A < _.

Base 64
7-bit ASCII
Code page 437 compatible
base64url alphabet, but different order
Safe URL and filename use
Excludes forbidden [v]fat chars: <>:"/\|?*</tt> - Excludes quoting chars: "'$ and space
Not supporting ASCII code-point sorting.
Order: 0 < a < A < _
