Hello,

I'm getting an error when querying a dcm4chee worklist from a Philips HD11 Ultrasound.

The error that I can see in the US is the following:

0x8d is not a valid code of ISO 8859-1 West European languages (Latin-1).

How did you populate the worklist? Via HL7 Order Message? What's the character set used by the HL7 messages?

How does the response look using dcm4che's findscu utility? e.g.:

$ findscu -M MWL -cPC43...@192.168.100.228:11112 $DCM4CHE_HOME/etc/findscu/mwl.xml

worklist entries come from an HL7 ORM (I don't know the character set used by the HL7, I don't have that info).

the response of the findscu is attached.

I tried to filter the query but I couldn't.

findscu -M MWL -m 00080060=US -m 00400001=RXD_ECO1 -c PC43...@192.168.100.228:11112 -- C:/dcm/etc/findscu/mwl.xml > test2.txt

There are non-ASCII characters in Requested Procedure Description and Code Values and Meaning, as in Scheduled Procedure Step Descriptions and in Scheduled Protocol Code Values and Meaning:

Guess the error happens on decoding the received HL7 ORM messages, caused by a wrong configuration of

https://dcm4che.atlassian.net/wiki/spaces/ee2/pages/2555986/HL7+Server#HL7Server-CharsetName , mismatching the actual charset of the received HL7 message.
