Despite many attempts to supersede it, straight ASCII text continues to live on.

All manner of mutually incompatible wordprocessor formats have been developed in attempts to displace it. None has succeeded -- even supremely powerful Microsoft's own Word format, a strange format that is incompatible with everything else including later incarnations of itself, has made only limited inroads against the humble straight text format. PDF has tried very hard to replace simple text, but it remains a doomed, backward-looking format for people who never understood the electronic age and retain an atavistic fetish for paper.

Only one format has succeeded in becoming at least as popular as ordinary text, and that is HTML, thanks to the web. But HTML won't ever supplant text because instead of competing with it, HTML actually uses ordinary text in a cunning technique to display different fonts and styles and to insert images.

In recent years HTML has begun to invade email -- one of simple text's most strongly held territories. But in an odd turn of events HTML's attractive styles and flexibility are proving an impediment, as spammers now use HTML's hidden tags to evade spam filters, and embedded images to identify people who view email. This has caused many people to simply spam-filter all unknown email to the trash if it contains HTML tags. This may be resulting in a slow return to using simple, honest, text emails.

Text has also experienced a popular resurgence lately in the form of SMS messaging. It will probably always be the most economical way to transfer information from keyboard to screen.

In the end, if you want to guarantee that your audience can read your message then simple text is still the only 100% sure bet. After about half a century of computing this is still true, and perhaps will always be.

Wow! Thanks for that. I would never have thought it possible. I didn't know domain names could take characters beyond the standard ASCII ones. Just goes to show we have to be careful. I never take links to sites that are important for working with money or similar serious stuff. I either type the address in myself or else use my bookmark. But that is because I've noticed a number of links that don't go where they say they do -- especially those scam emails pretending to be from banks or PayPal. If you hover the mouse over the name and look at the status bar, or right-click and choose copy address you'll often notice the numeric address of the scammer's website. Even hovering over the address is not a guarantee of exposing the scam though, because if you have javascript turned on in your email client (and I can't think of any good reason to do so) then it could write a bogus address to the status bar, so that all would like hunky dory.

But the exploit you mention is more dangerous because the page could look genuine even if you copy and paste the address. The only thing I can think of is to paste the address into a simple text editor (not a word processor) that has a basic ASCII font and that will reveal the con.
