the double-backslash is necessary because you're escaping for bash.
compile: make
install to /usr/local/bin: sudo make install
Linux suggestion: create the bash alias
alias copy='xclip -selection c'
then you can do:
tex2uni \\Sigma | copy
to copy the unicode character directly to the X clipboard.
Mac OS suggestion: use the pbcopy utility to copy the unicode character directly to the Mac OS clipboard:
tex2uni \\Sigma | pbcopy
tex2uni will not output a newline character if it detects that stdout is anything other than a terminal.
