I could easily remove any non Persian (Farsi) characters using this function, the range for Arabic and Persian are shared so this code could be used for Arabic too.
<?php mb_ereg_replace("[^-ۿ]","-",$string); ?>
This is the reference for finding the character range of Unicode languages:

mb_ereg
(PHP 4 >= 4.2.0, PHP 5)
mb_ereg — Regular expression match with multibyte support
Description
int mb_ereg
( string
$pattern
, string $string
[, array $regs
] )Executes the regular expression match with multibyte support.
Parameters
Return Values
Executes the regular expression
match with multibyte support, and returns 1 if matches are found.
If the optional regs parameter was specified, the function
returns the byte length of matched part, and the array
regs will contain the substring of matched
string. The function returns 1 if it matches with the empty
string. If no matches are found or an error happens, FALSE will be
returned.
Notes
Note:
The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.

Hebrew regex tested on PHP 5, Ubuntu 8.04.
Seems to work fine without the mb_regex_encoding lines (commented out).
Didn't seem to work with \uxxxx (also commented out).
<?php
echo "Line ";
//mb_regex_encoding("ISO-8859-8");
//if(mb_ereg(".*([\u05d0-\u05ea]).*", $this->current_line))
if(mb_ereg(".*([א-ת]).*", $this->current_line))
{
echo "has";
}
else
{
echo "doesn't have";
}
echo " Hebrew characters.<br>";
//mb_regex_encoding("UTF-8");
?>
