grep 2.25 only stopped treating files as binary under the "C" locale, as that commonly means "I don't care about the encoding". AFAIK the behaviour did not change if you call it under a proper locale such as sv_SE.UTF-8. If you look at the file when it's encoded in a proper locale, it works:
$ iconv -f iso8859-1 -t utf8 /tmp/seen-binary-by-grep.txt vMgs ingen lösning - the Swedish character o-umlaut osmak ingen lösning smak lösningen - the solution (Note that the file is broken -- the first two non-ASCII ö characters are encoded in ISO-8859-1, and the last one is UTF-8). And as described above, binary detection also is disabled under C: $ LC_CTYPE=C grep ning /tmp/seen-binary-by-grep.txt vMgs ingen l�sning - the Swedish character o-umlaut osmak ingen l�sning smak lösningen - the solution So this is indeed not the same bug as bug 1547466, I retitled that one to clarify. It's much closer to http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19985. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to grep in Ubuntu. https://bugs.launchpad.net/bugs/1535458 Title: [15.10 REGRESSION] Randomly wrongly detects files as binary Status in grep package in Ubuntu: Confirmed Status in grep package in Debian: Fix Released Bug description: I have a folder with a bunch of subfolder and several hundred or thousands files, most of them PHP files (obviously text). I often use grep recursively, like this: $ grep -R somepattern * Since the upgrade from 15.04 to 15.10, it often happens that a lot of text files are wrongly treated as binary. That means that, when a match is found, instead of getting the normal output which would show the file name and the matching line (with the matching substring highlighted), I get the bogus message: binary file whatever.php matches Just to be clear: in one invocation of grep -R, I get mixed output with a lot of matches shown in the expected way and quit e a few matches shown in the wrong way, even though ALL matching files are text files. This worked as expected before the upgrade from 15.04 and 15.10. This is a HUGE issue that makes it impossible to do everyday developing work. Until you fix it, please f***ing roll back grep to the previous version, because this sh** is unusable.
