PlantUML Text Encoding
PlantUML uses a special encoding to transform a uml text description like:
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
into

The advantage of the last encoding is that it is easier to use in URL.
To achieve such an encoding, the text diagram is:
- Encoded in UTF-8
- Compressed using Deflate algorithm
- Encoded back in plain ASCII using a transformation close to base64
You can use -encodeurl or -decodeurl in the command line flags to encode or decode the text.
You will find here some implementation of this encoder:
