In each line of file, I wish to check if word1 is a non-connected subset of any of the other words in the line. If yes, keep only the words that ward1 is a subset of. Else, remove the whole line.
Also, I want to remove the letters that word1 doesn't match with, except for "_+"

vt-is-utf8
VT-IS-UTF8(1) Linux User's Manual VT-IS-UTF8(1)NAME
vt-is-UTF8 - check whether current VT is in UTF8- or byte-mode.
SYNOPSIS
vt-is-UTF8 [-h|--help] [-V|--version] [-q|--quiet]
DESCRIPTION
vt-is-UTF8 checks whether the current VT is in UTF8 mode, by writing (and erasing afterwards) a 3-byte-long UTF8 sequence, and looking how
much chars where displayed by the console driver.
A message telling in which mode the console is is then written to stdout (except if the --quiet option was given).
If the --quiet option is not given, the value returned is 1 if an error occurs, else 0.
OPTIONS -h --help
display version number, a short help message and exit.
-V --version
display version number and exit.
-q --quiet
do not print on stdout in with mode we are, but return the state as exit-status 1 if in UTF8-mode, 0 if in byte-mode. In case of
error, 0 is returned and a message is displayed on stderr.
BUGS
The check should be done by directly asking the kernel, which is not possible as of kernels 2.0.x.
As of kernel 2.0.35, the byte-mode is sometimes erroneously detected as UTF8-mode, after switching from a 512-chars font to a 256-chars
font. This is probably a console-driver bug.
