I saw many topics talking about this subject but nobody really answer:

- I use this gzip\_lines codec to extract log information from .csv files contained within .gz files
- the codec used in the input section is uptodate

=\> the content of .csv files is apparently not read by Logstash; the message is: "general error reading C:/Backup/data/logs/res\_LSAG\_20171210\_104.csv.gz - error: java.lang.IllegalArgumentException: Object: ?┐-Z res\_LSAG\_20171210\_104.csv ı?M?Ë0?´³ is not a legal argument to this wrapper, cause it doesn't respond to "read"." See the image below.

My code is:  
input {  
file {  
path =\> "C:/Backup/data/logs/\*.gz"  
sincedb\_path =\> "C:/Backup/Logstash/db/test.db"  
start\_position =\> "beginning"  
discover\_interval =\> 10  
stat\_interval =\> 10  
close\_older =\> 300  
codec =\> gzip\_lines {  
charset =\> "UTF-8"  
#charset =\> "ISO-8859-1"  
}  
}  
}

Any idea?
