Thumbs down Removing Illegal Characters in the MSH

How can I remove some illegal characters that are showing up at the beginning of a MSH segment? They are non-ASCII characters and I think they are hexadecimal EF, BB, and BF. I am pretty sure I need to do this in the pre-processor, but I cannot figure out how to do that. I have tried to replace the characters with null, but that is not working. Here is what I am getting:

Code:
MSH|^~&|CARDIONET|CARDIONET|MEDITECH|Conshohocken|20151205152943+0000||ORU^R01|0afd3f55-d5bc-4532-abb6-14d3dacbc5ee|P|2.3|
I highlighted the illegal characters I would like to remove in red. Any suggestions are greatly appreciated!!!!!!


Thanks!

Looks like an XML BOM to me. You should be able to remove it in the preprocessor script:

Code:
return message.replace(/\uFEFF/g,'');

Always include what Mirth Connect version you're working with. Also include (if applicable) the code you're using and full stacktraces for errors (use CODE tags). Posting your entire channel is helpful as well; make sure to scrub any PHI/passwords first.

We got it working by placing the following in the pre-processor:

return message.substring(3);

The messages were a predictable length of 3 character preceding the message.
