Let's take a different view angle.
The problem is not really about encoding something like "decimals numbers" 0..127 into base-15 (which is messy). It's about converting a base-127 string into base-15. If you can see it that way, then it's just the same principle as with converting from, say, base-16 (hex) to base-10 (decimal), or base-10 to base-2.
