TeX already treats 'carriage returns' as spaces unless it is broken.

Carriage return has character code 13(dec), or ^^M.
Line feed has character code 10(dec), or ^^J.

^^K has character code 11(dec) ('Vertical Tab').

Line breaks are ^^J under UNIX, ^^M under Apple, and ^^M^^J under

UNIX TeX accepts files which had been written under Windows, hence it
treats both, ^^M and ^^J, as spaces.

It's best to check first where the ^^K comes from.  What happens if
you type

    tex story

If this works, then there is something wrong with your editor.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
