That is an escape sequence = escape[0m escape = ^[

Escape sequences do funny things to terminal output, like change the color for example.
You probably have different escape sequences being sent to the terminal. Trap the ouput in od:
Code:
grblib somefile.cpp | od -c

This will let you see exactly what is being output
ansi escape sequences:

ASCII Table - ANSI Escape sequences

Finally once you know which bits of garbage to filter, you can use sed to filter them out.
Code:
grblib somefile.cpp | sed 's'/<garbage>//g'

I do not know what junk is being produced.

Note: You may also want to check your terminal settings.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
