When I redirect Maven commands, the file looks wrongly encoded

Question

When I run a Maven command, it's normal in the terminal. But there is a problem when I redirect the output to a file like this:

mvn install > file.log

When I open the file, I see:

[[1;34mINFO[m] Scanning for projects...
[[1;34mINFO[m] 
[[1;34mINFO[m] [1m------------------------------------------------------------------------[m

Does anyone know what the problem is? My Ubuntu is 17.10.

The program mvn, whatever it is, wants to colorize its output and seems to do this even if standard output is not a terminal. Look for an option to disable colorizing the output. — AlexP, Dec 05 '17 at 12:10
They look like ANSI color codes - have you tried running in batch (-B) mode as described here Maven CLI Options Reference ? — steeldriver, Dec 05 '17 at 12:10

Hat tip to @Douglas: it appears that the required option is mvn -B.
