Talk:Binary-to-text encoding
basE91
Uses 91 characters, and every pair of characters represents either 13 or 14 bits. Since 2^13 < 91*91 < 2^14, two characters can encode all 13-bit strings and some 14-bit strings; since 91*91=8281 and 2^13=8192, there are 89 combinations of two characters that are not used for representing strings of 13 characters. The particular choice is: for a string of 14 bits, if its lowest 13 represent a number greater than or equal to 89, the two characters are used to represent only these 13 bits; otherwise, 14 bits are encoded.

reviving 'ascii armor' concept
ASCII armor was apparently the original title of this article. It is now 'binary to text encoding'. The ascii armoring concept consists of more than just encoding binary into ascii, it also consists of encoding
