Thanks, Mitch Freeville, NY Not a VIM-based method, but there is a Perl script called Demoroniser (http://www.fourmilab.ch/webtools/demoroniser/) which is designed to handle a lot of these characters and convert them into ASCII characters.

Mitch Wiedemann wrote: non-visually detectable characters (which I assume are high ASCII) If I may nitpick, high ASCII is not the right terminology here. The ASCII table only contains 128 characters, with codes 0…127 (where only codes 32…126 have a visual representation.) What you call high ASCII are Unicode characters that are autside ASCII, or Latin-1 characters that are autside ASCII. In both cases they have codes greater than 127. Is there a way I can have my Vim highlight these characters so I can see them and replace them with their HTML counterparts? I usually do a :set hls (highlight search results) followed by /[^ -~] (search for any character that is not between space and tilde, ie. that is not a printable character from the ASCII set.) You can add the tab character (with Ctrl-V Tab) inside the square brackets if you use it in your documents. It will show as /[^ -~^I] with a blue ^I. This has the added benefit of hitting n to get to the next one. Tobia
Re: highlighting weird characters... Thanks everyone!
Thanks everyone for your suggestions! I'm now looking around for a typical document that I can paste in to use a a guinea pig. Viva la Vim!

I've added two new maps to my ~/.vimrc maps to quickly find Unicode characters within the document map ,uni :match Error /[\x7f-\xff]/CR map ,uni2 /[^ -~]CR I've found both methods useful, one just highlights (allowing me to /find other stuff) and one highlights via /find. Neat. Thanks again for the help.

No idea about highlighting, but exactly to replace strange characters with HTML or LaTeX or anything else or to do it in backward direction I've write this plugin: http://www.vim.org/scripts/script.php?script_id=1761 Documentation inside.

I've searched Google, the Vim e-mail archive, and I've helped Ugandan children :), but I'm no closer to the answer. Any hints? One way to do this would be to :set isprint= which will tell vim that only the characters in the range 32 - 126 are printable. Vim will then highlight all the other characters as SpecialKey. You can then search for these non-printable characters with /[^[:print:]] Another, probably better, way would be to simply search for /[^Vx80-^Vxff] where ^V means a literal Ctrl-V. That will search for any character in the range 0x80 - 0xff and will highlight them all with the Search highlight if 'hlsearch' is set. I think this way is better because it preserves vim's rendering of the non-ASCII characters, which may make it easier for you to choose their replacements.

Well, if you want to highlight them, you can do something like :match Error /[\x7f-\xff]/ which should catch most of the offenders. Or you can search for them with the same regexp. And if you have :set hls, it will highlight them too. :) It does require certain knobs to be set properly in your 'cpoptions' setting, but if you run vim (rather than vi), they should automatically be set unless you had reason to bung with them. Once you're on a particular one, you can use ga to determine the ASCII value of the character in question, and can use that value for searchreplace. Hope this helps, -tim
