Description

ASCII control characters are not escaped when the ctf-text format prints strings or text arrays, leading to interesting results.

Simple steps to reproduce:

lttng create bug
lttng enable-event -k lttng_logger
lttng start
echo -ne 'hello\nworld\x08\x08\x08man\x00true end' > /proc/lttng-logger
lttng stop
lttng view

Babeltrace shows:

[15:04:54.524520321] (+?.?????????) archeepp lttng_logger: { cpu_id = 0 }, { _msg_length = 25, msg = "hello
woman" }
