This is messy and if you decide to change how you wanted to parse the encoded data, you'd have to change the function calls in 2 places. Character set: In case of textual data, the encoding scheme does not contain the character set, so you have to specify which character set was used during the encoding process. It should be accessible to anyone with a little bit of computer science experience and a bit of familiarity with certificates. UTF-8 is 1:1 or 1:2 .. and ideally it also is 200% more 50% of the time or 2:3, which is actually +50%, so encoding in utf-8 is often worse than just using a base64 … Yes, npp has plugins to do it (TextFX being the main one I've used).
