23885[Clip] Re: alphanumeric character transcoding, by ones and pairs
- Jun 18, 2013Flo and Ian,
I apologize for not noticing this earlier, but you two seemed to be doing so well without me, I was afraid I'd break your focus.
If "bJ" occurs together it becomes a single and different character.
If "bj" occurs together it is two separate characters. These are completely case sensitive pairings.
ONLY these character pairs follow this rule:
"bJ" >> "bS"
"dD" >> "'f"
"kY" >> "uF"
"KY" >> "cF"
"mD" >> "rf"
"mJ" >> "rS"
"pJ" >> "yS"
"PJ" >> "zS"
"SJ" >> "pS"
"sJ" >> "qS"
