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.
