base128 is easier to encode/decode than base64 - you just use shifts and masks. Can be important for embedded implementations. base128 makes slightly more efficient use of the transport than base64 by using more of the available bits. People do use base128 - I'm using it for something now. It's just not as common.

Base128 strings is viable for everything (variables, localStorage, even sending because HTTP and modern servers is 8-bit clean) but not files (except latin1). To store a string as UTF8 file it restricts to maximum Base128 (7 bits), because the 8-th bit is used in UTF8 to know if it is an ascii (bit is 0) or a unicode (bit is 1 to store in more ...

Jun 5, 2013 · I would strongly recommend against Base128 encoding if you can avoid it. A 7 bit alphabet would have to contain unprintable ASCII control characters (there are only 94 printable characters aka below codepoint 0x20). Many systems will fall over if …

Jul 15, 2013 · Your best bet is to use the ToBase64Transform and FromBase64Transform crypto interfaces.. The basic gist behind this code sample is that you use the From/ToBase64Transform transform class with the standard crypto stream to handle the heavy work of converting the incoming data to or from base64.

Nov 2, 2018 · After conversion bytes array to base128 string (which is valid json) the output string is less than 15% bigger than input array. Update. A dig a little bit more, and expose that when we send characters which codes are bigger than 128 (¼½ÀÁÂÃÄ...

Feb 2, 2021 · Why is base128 not used? If we want to represent binary data as printable characters, we can hex encode it using a set of 16 printable 'digits' from the ASCII set (yielding 2 digits per byte of data) or we can base64 encoding using a set of 64 printable characters of the ASCII set (yielding roughly 1.33 characters per byte of data)

Sep 25, 2008 · Advantages of base128 encoding a)occupies less space when compared with base64 encoding (base128) b)when data is being transmitted by base128 encoding it makes the data transfer easier as only less amount of data needs to …

Feb 12, 2011 · The preference though should be Base128, which uses "varint" encoding, so small numbers take less space to encode. Additionally, this prefix style can be used to make a sequence of objects wire-compatible with a single object with a repeated field, which has some useful applications.
