For now we only support 4 out of 6 different delimiters.
We are currently missing the Decimal mark delimiter (.). The other delimiter is the Repetition separator but it is not supported in some versions of edifact.
I made some modifications and pushed up 3d9f3f91a5766cc4c77ff056de198415c14a7cf4, which is basically the changes you had here but with a few changes. Thanks for the contribution :v:
