<p dir="ltr">Hi,</p>
<p dir="ltr">Do i understand correctly that you added <U+1F633> in place of utf8 sequences in the email and the file contains utf8 encoding of the same value?</p>
<p dir="ltr">My theory right now is that elastic uses a 16bit representation of unicode codepoints, and 1f633 doesnt fit there. But I couldnt come up with plausible explanation how it would become ð<U+009F><U+0098>³</p>
<p dir="ltr">Syslog-ng uses utf8 internally, so it should work with long utf8 sequences without problems. Do you perhaps have an encoding() option at the elastic destination?</p>
<p dir="ltr">It could also be a problem in the elastic java plugin, I dont know how we supply the data. @juhaszviktor do you see any chance of this happening in the java code?</p><div class="HOEnZb"><div class="h5">

This is the same conent that is sent to the elasticsearch destination -- option("message-template", "$MESSAGE\n")<br>

<br>
<br>
<br>
Note that the source has unicde data as <U+1F633><br>
The elasticsearch destination is sent <U+1F633><br>
but the elastisearch server logs ð<U+009F><U+0098>³<br>
<br>
The elasticsearch server also seems to end the message with the text<br>
<br>
"FACILITY":"mail<br>
<br>
when it should end with<br>
<br>
"FACILITY":"mail"}<br>
<br>
so it is missing two characters.<br>
<br>
Does anyone want to guess at what is happening?<br>
<br>
Should I post to the elasticsearch group with the reasoning that the source (syslog-ng) and the destination (elasticsearch) need to be configured with the same unicode settings?<br>
<br>
Thanks,<br>
