Console output is garbled in datalogs

[rzblue]

The console output added in #6977 is garbled (seems to be missing lots of characters):

(the first 3 lines occur before datalog starts, so those are expected to be missing from the output)

FRC_TBD_2624151fddf7ef7c.wpilog.log

[spacey-sooty]

It appears whitespace characters like \n are being excluded as \ and n.

[rzblue]

Newlines should be getting stripped from the output, it should be outputting one log entry per line. What do you mean by "getting excluded as \ and n"?

The missing characters aren't newlines, they're just characters in the middle of a line. I have a few ideas what it could be, just need to debug it on a rio.
