Hi everybovy, I'm trying to parse a log file and i'm facing a case that causes an error message when i test my filter. in the last field, it sometimes begin with a tabulation (not several blank spaces). Example : `2015-07-28;16:32:06;Level(8,Information);Id(0,None); url= C:\ProgramData\Tests` i don't know how to escape this tab, or deal with it to avoid having this error message : **Error in line 5, char 81: invalid character '\t' in string literal** Thanks a lot for any help or suggestion.
