This is a clumsy way of saying you don't like the '©' character in strings.
I truly do dislike the fact that that you changed the behavior of strings.
Yes, I know I can figure out how to change my code to use byte arrays
somehow or another, but it is a lot of work.  More than just "sed 's/string/bytes/'"

Anyway, seg faulting is not a good response.

(gdb) printf "%s\n", pDE->de_val.dvu_text
This program reads or accepts a list of files and prints the names of the
files that are not plain text.  @i{plain text} characters are characters
in the range of 0x20 thru 0x7E (' ' thru '~'), plus backspace,
whitespace characters and the character 0xA9 (© - the circled-C copyright
character).
