@zigh-code do you could you provide some more information? sample hl7, hl7v2 version, perhaps even a unit test or code example?

[zigh-code]

I'm using the last version of the package.
The version of Hl7 in my case is 2.5 (string data),

If I try for the TQ1 segment, it work

But when I try with ODS, there is an issue

Data Test:

 string omdText = "MSH|^~\\&|EDITE|TEST|TEST|TEST|20210519141200||OMD^O03^OMD_O03|202105191412001|P|2.5|||||FRA|8859/1\r" +

@zigh-code thanks for the extra info, will take a look when I can.

@zigh-code sorry for the long delay in getting back to you, I think I found the issue, its related to how java and dotnet use regex slightly differently so basically a bug in the port.

I will hopefully have a PR for this in the coming days.

@zigh-code I have put up a PR to fix this and included a unit test to prove it works.
