Text::Striphigh - Perl extension to strip the high bit off of ISO-8859-1 text. |
NAME
Text::Striphigh - Perl extension to strip the high bit off of ISO-8859-1 text.
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
SYNOPSIS
use Text::Striphigh 'striphigh'
$SevenBitsText = striphigh($TextContainingEightBitCharacters);
DESCRIPTION
The Text::Striphigh module exports a single function: striphigh. This
function takes one argument, a string possibly containing high ASCII
characters in the ISO-8859-1 character set, and transforms this into a
string containing only 7 bits ASCII characters, by substituting every
high bit character with a similar looking standard ASCII character, or
with a sequence of standard ASCII characters.
Because of precisely the deficiency this package tries to offer a workaround for is present in some of the things that process pod, there are no examples in this manpage. Look at the source or the test script if you want examples.
MAINTENANCE
If you ever want to change the striphigh function yourself, then don't
change the one containing the mile long tr{}{} statement that you see
at first, change the one behind the __DATA__ that's a lot more readable.
After you've done that, simply run the Striphigh.pm file through perl
to generate a new version of the first routine, and in fact of the entire
file, something like this:
perl -w Striphigh.pm > Striphigh.pm.new mv Striphigh.pm.new Striphigh.pm
BUGS
Assumes the input text is ISO-8859-1, without even looking at the LOCALE settings.
Some translations are probably less than optimal.
People will be offended if you run their names through this function, and print the result on an envelope using an outdated printing device. However, it's probably better than having that printer print a name with a high ASCII character in it which happens to be the command to set the printer on fire.
