That wouldn't precisely be an issue when using the -F option:

-F, --fixed-strings
    Interpret PATTERN as a list of fixed strings, separated by newlines,
    any of which is to be matched.  (-F is specified by POSIX.)

However, it is a good point nonetheless since, if the .txt file contains
\r\n line endings the \r may be interpreted incorrectly.
