Characters go missing during round trip

[euporos]

Hi I'm making good use of the library for one of my projects – thanks for making it available. I did have to work around one problem though, as shown in the following example (RunKit)

train = "[1300 [[57 4.56 0.12 11 10260 240] [8.600000000000001 5.2 0.44 44 16447 142] [8.600000000000001 240.8 0.08 12 930] [8.600000000000001 0.16 4.63 230 1080] [8.600000000000001 482.1 2.82 490 572] [8.600000000000001 135.1 28.67 820 1185]]]"

troublesomeInput = "[1300 [[56 4.56 0.12 11 10260 240] [44 5.2 0.44 44 16447 142] [0 240.8 0.08 12 930] [0 0.16 4.63 230 1080] [0 482.1 2.82 490 572] [0 135.1 28.67 820 1185]]]"

let Encoder = huffmanUrlCompressor.createEncoder(train);

let encodedParam = huffmanUrlCompressor.encodeConfig(troublesomeInput,Encoder)

let decodParam= huffmanUrlCompressor.decodeConfig(encodedParam,Encoder)

decodParam turns out as:

[1300 [[56 4.56 0.12 11 10260 240] [44 5.2 0.44 44 16447 142] [0 240.8 0.08 12 930] [0 0.16 4.63 230 1080] [0 482.1 2.82 490 572] [0 135.1 28.67 820 1185]]

As you can see, the trailing Bracket has been lost in the process. Any idea as to what may be causing this behaviour?
