The Charset tool
Browser on different operating systems don't display all characters the
same way. If no "charset"-declaration is included in a web page, it
should be interpreted as "iso-latin-1", i.e. western european 8-bit
encoding. Characters encoded in the &#nnn; form are to be
interpreted as coming from this character set. But some browsers,
especially on the Mac, don't get this right (or i might have it wrong ;-)
The characters in the "undefined " range (128 .. 160) are open for
arbitrary re-interpretation, anyway.
The charset tool displays the characters 0 .. 255 in two ways: as straight
8-bit characters, and in &dec; numeric encoding.
You can call the tool with an option "page" to determine the character page
to be shown. using charset.pl?page=1, you can look at the character
256..511. If you display pages > 1, only the numeric encoding will be
shown.
A few hints: page 5 contains hebraic; page 6 arabic, page 32 contains differently-sized
spaces. IE5 on NT shows some of the characters; NS4.7/NT doesn't.
