base128like

base128like is a theoretical or conceptual encoding scheme that suggests representing data using a base-128 numerical system. In a base-128 system, each digit can represent values from 0 to 127, inclusive. This is in contrast to common encoding schemes like Base64, which uses a base-64 system and typically employs ASCII characters for representation.

The primary advantage of a higher base, such as 128, is potentially greater data density. A base-128 encoding would require fewer "characters" to represent the same amount of binary data compared to lower bases. For example, each base-128 digit could represent 7 bits of information (since 2^7 = 128). This is an improvement over Base64, where each character represents 6 bits (2^6 = 64).

The practical implementation of a base-128 encoding would depend on the chosen character set for its digits. Unlike Base64, which has a well-defined set of 64 characters (A-Z, a-z, 0-9, +, /), a base-128 system would need to select 128 distinct characters. This could be problematic as it might require a larger character set than typically available in some contexts, or the use of control characters which can have special meanings in various communication protocols. Therefore, while theoretically more efficient in terms of space, base128like has not seen widespread adoption, partly due to the challenges in defining and handling its character set.
