Not necessarily in the code, but the data we save. Let's say you mix at som=
e=20
point some info from the source and the data storage *be it ZODB or gettext=
=20
file). If your strings are not in the right format you run in all sorts of=
=20
problems. I guess only developers who have been in unicode hell once,=20
understand... :-)

> And what makes a text string? =20

Good question. That needs to be well defined and really depends on several=
=20
factors. The easiest way is to check whether a string cane ever contain=20
unicode chars.

> Is a filename a text string?

Well, can filenames contain unicode characters?

> A Python attribute name? =20

No, sinc ethey can only contain ASCII.

> An XML attribute name?

Definitely, since the XML standard says that everything in XML can contain=
=20
unicode strings. (I think.)
