Code:
perl -lne 'print "$ARGV:$.:error: $_" if (length != 26)' file

... or even simply

Code:
egrep -v '^.{26}$' file

The warnings are unrelated. The Perl command printed what you wanted it to print (the last two lines of output; the output consists of file name, line number, "error: ", and the contents of the input line).

To work around the locale problem, you can use LC_ALL=C perl -lne ... but you should really see to it that your locale settings are fixed permanently; many applications will issue warnings about this problem, not just Perl. Perl is just a bit more verbose about it than many other applications.

The egrep command prints only the same two lines for me. Maybe you have DOS carriage returns or something in the input file? Or just spaces -- trailing spaces count as characters, too.

Code:
vnix$ egrep -v '^.{26}$' <<HERE
