[HAPI-devel] Character encodings

[Lorenzo V. <Lor...@ev...>]

Hi at all.

After reading this page (https://hapifhir.github.io/hapi-hl7v2/xref/ca/uhn/hl7v2/examples/HandlingCharacterEncodings.html) I have few questions about the reported instructions.
I hope that someone can help me to clarify all my dubs.
Below my questions.

1.       In the page is said that "By default, MinLowerLayerProtocol uses the "US-ASCII". This is also true by using the last method in the page (line 76 of the page) if segment MSH-18 is not specified?

2.       With the first method (line 40 of the page) if I set the character encodings to "UTF-8", the messages in "US-ASCII" are also received correctly?

3.       What is the main difference between the method in the line 40 and the method in line 76? Only the use or not of the segment MSH-18 (if present)?

4.       If I want to read at a later time an HL7 message, I must use the character encoding used when I had received this message?

Thanks for your times,
Lorenzo.
