Most apps that deal with this have a "default encoding" preference which the

OS's locale?
Yes, Chandler's default locale is derived from the OS or can be set with the
--locale command line flag. Defaulting in such a way works best when 'most'
data is from the same locale and text in the same language.
A US user working with personal data and international projects can go a long
way with en_US. On the other hand, a Spanish user may be having a mix of
spanish data (for example, personal email) and english data (for example,
email from open source project mailing lists) and having some way of
specifying the language of the text being worked with can help in better
indexing and searching it later.

Andi,
What do recommend doing in the case where a locale is not know for the
text?
Email is a great example, in most cases no language (locale) headers are
supplied.
When no locale is supplied, the encoding supplied could be used for clues
for
using a set of heuristics helping to 'guess' a locale. In the case of
email, for example, the domain of the sender may also provide a clue.
That guess may be better than nothing but not by much...
A good guess at this is important for full text indexing.
When sorting email addresses, however, I'd think that the Chandler user's
locale would prevail over the potential locale of the data being sorted.

One issue to remember, if we are sorting on the name of the user i.e.
Brian Kirsch <[EMAIL PROTECTED]> then the sort order will need
to be localized with PyICU.
Last year, I added a new index class called StringIndex. It understands
locale and uses PyICU's collator support for comparing strings.
Similarly, I realized recently that for full text indexing's sake, LOBs
(at least, if not all attributes) should also have a locale aspect so
that when full text indexing (and queries) are run, an analyzer that is
appropriate for the language of the locale is used to break up the text
(or queries) in tokens.
