[Zope-CMF] .metadata files, latin-1 vs. unicode, and encoding errors

[Doyon, Jean-Francois]

Hello,

My app started throwing unicode errors, and I've tracked it down to the fact I have accents in .metadata files.

This becomes a problem when a unicode string sneaks into the page to be rendered, at which time StringIO.getvalue() bombs.

Normally I'd try to get rid of the unicode string, but in this case it seems like it's coming from the i18n machinery (The result of a translation), and as such, might not be very desirable for me to mess with it.

For example I have an FSImage with a title that in french contains an accented character.

When calling the tag() method on the image, I end up with a <type 'str'> with high bit characters.

The same page will contain i18n:translate results, which are unicode.

And voila.

I tried making the FSMetadata logic return a unicode string instead of a regular string, but that didn't work (not too clear on why, the logging module started throwing errors?).

I also tried using HTML entities such as &eacute; in there, but looks like HTML title= or alt= doesn't render them?

Anyone have any ideas how I might get around this?  I'm out of ideas :(

Thanks,
