How to decode and print base64 with unprintable character

Hi, I have a encoded64 string that I want to decode and print as string, it should be human readable
Example:

iex(33)> {:ok, bb} = Base.decode64("g2gCbQAAAA5zaGFocnlhcnMtaU1hY20AAAAIYcJbhqjzRj4=")
{:ok,
 <<131, 104, 2, 109, 0, 0, 0, 14, 115, 104, 97, 104, 114, 121, 97, 114, 115, 45,
   105, 77, 97, 99, 109, 0, 0, 0, 8, 97, 194, 91, 134, 168, 243, 70, 62>>

Now how can convert bb to string?

Thank you.

Garbage in, garbage out. You need to determine the source of the data, and find out what format it is stored in, in order to work out how to decode it.

It’s not for sure that. It’s a best effort guess at what the source might be – replacing any unknown things with this fancy ? character. This often works ok for any single byte, possibly ascii, characters, because a lot of charsets match in the ascii characters range, but all bets are off for other characters / multi byte sequences.

Where Next?
