What's the best way to store binary

Question

Ive recently implemented Hoffman compression in c++, if I were to store the results as binary it would take up a lot more space as each 1 and 0 is a character. Alternatively I was thinking maybe I could break the binary into sections of 8 and put characters in the text file, but that would kinda be annoying (so hopefully that can be avoided). My question here is what is the best way to store binary in a text file in terms of character efficietcy?

If you can store the data as-is, then do so (in other words, do not use any encoding; simply save the raw bytes).

If you need to store the data within a text file (for instance as a paragraph or as a quoted string), then you have many ways of doing so. For instance, base64 is a very common one, but there are many others.
