The perl version is v5.6.0 for hpux when I search using =~ any string that contains \P such as \\Printer1\P1275 I run into this error Can't find unicode character property definition via main->5 or 5.pl at unicode0 How can I disable perl from thinking \P is a unicode character? Thank You

    Because 

    /$regex/

    [download]
    interprets the contents of $regex as a regular expression. What you want is: 
    /\Q$string\E/

    [download]
    which interprets the variable contents as a string (by backslashing any non-"word" characters the same as quotemeta does).

    Any literal backslashes in regular expressions need to be escaped: \\\\Printer1\\P1275
