  But there is still the problem with running off the end of the source - If the source is not a multiple of 3 bytes then the input iterator will run off the end of the input sequence which can cause an error.

  I had to separately record the number of bytes.  Then when I decode, just pull off that number of bytes.

    Hi,

    I'm trying to encode base64 data by composing base64_from_binary with transform_width but this doesn't appear to work correctly when the data is not a multiple of 3 long. What is the correct way to handle this  - do I have to handle the padding myself by extending the input data and then patching the tail of the result?

       Thanks

           Andrew
