why hebrew shows in one page and doesn't in another?

The following shows weird characters:

but here it shows no problem:

You need to properly set the character encoding (charset) for the page.

On the page where the characters are displaying correctly, you have it set to UTF-8:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

The UTF-8 character set includes Hebrew characters, so it has no problem displaying them correctly.

On the other page, you've got it set to ISO-8859:

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

The ISO-8859 character set does not include Hebrew characters, so it gives you a garbled mess instead.
