I used to apply certain unicode characters on a HTML-page, because these sets not only contain characters, but also more pictogram-like shapes, which can be used as a 'graphic' element.
Of course I can't expect, according to my language-settings, that the set with chinese or nepalese characters is correctly represented. Then a rectangle or question mark is shown.
So I tested which ones would still work, like the mathematical set, and which don't. It resulted in this page :

Until I recently heard of differences in the representation by the browsers (I use FireFox).
So I ask e.g. Exploder users to check this page to see if all is correctly shown.
If not, report please, so I can adjust my use of these options, so the outcome is sure to be common.

Seems to work fine in Opera, but Exploder sucks with the default settings. Perhaps there is a fix by changing some encoding option somewhere.

Edit: I don't know what the default webpage font is, but I had mine set to Verdana. When I changed it to Lucida Sans Unicode, a lot more of the characters displayed correctly. I guess it will look OK for people using MS Unicode or Code 2000.

Interesting that PNGOUT saves a lot of space on these files (< half the size).

Hi Sam,
I can see the characters in Opera 9, Netscape 8 and Firefox 1.5 from USB memory stick.
I don't see them in IE 6 and NetCaptor 7. NetCaptor is only a shell (a nice one) of IE.
I don't use IE 7.

Thanks for the reactions.
Bhikkhu, you're right, I forgot about the aspect of the chosen font.
I just checked in the HTML source, and I didn't declare any font. So I guess it's set by Firefox to Times New Roman.

This outcome with IE is dramatic. I withdraw my intention to adjust the range of options. I just don't care anymore.

Interesting remark about the use of PNGOUT. Didn't seriously used it so far.
While I'm always seeking for the smallest filesize, if publishing on the web, with the least quality loss.
But also with the least amount of non-relevant data, so with screenshots like this, I start with reducing the number of colors.
As low as possible, without loosing things. PNG is a nice format to handle this.

K-Meleon, with font prefs set for sans-serif - Tahoma
Quite some page :)

An example how unpredictable it can get. This is part of the "Block Elements" section with Range: 2580–259F.

I removed the html-file of the link above, to replace it for a zipped version (http://www.xs4all.nl/~samzen/download/unicode_list.zip) including 7 pictures with blocks of the page.

Now I have the whole code, what can I do with it? How can I use these in my homepage? And why?

Opera 8 and Opera 9 displayed unicode_list.html with the columns very far apart. The more characters were missing in the given font, the more spread out columns were.

I declared to use Arial Unicode MS and only then the page loaded normally.


<style>
body {font-family: "Arial Unicode MS"}
</style>

Such a list could be useful for web designers running Win98 or similar simpler OS. Under NT we can just execute Charmap and get the whole table with number displayed in statusbar.

When starting this, I had no illusion at all about the aspects of compatibility of systems or settings qua reproduction.
I just wanted to make this list in a HTML format together with some representation of the code, as an example.

The HTML format offers the possibility to copy the proper code "&amp;#xnnnn;" to directly paste it in a new page.
So maybe it's more a kind of library, with possible examples of appearance.

Yes, and thank you for your effort. Never know how handy such a library can be in future's need.
