ST3: Why "Find in all" says text file is <binary>

[NeOnD]

Hi,
I’m trying out ST3 build 3126.
I have a text file (file.txt) which contains few lines with non-readable characters, otherwise the file is fully ASCII. When I try to look for some string using “File in files” (Ctrl+Shift+F) in this file the results show count of occurrences but doesn’t show any lines, rather it just says “”. I agree there are some binary characters in the file but it doesn’t qualify for it to treat whole file as binary & not to show any lines containing strings. Is there a tweak/option I can set to override this behaviour. If it’s an expected behaviour can you can fix it or atleast put some option?
