No, Xapian should handle arbitrary data. The UTF-8 parsing copes with
broken UTF-8 too.

Which xapian-bindings version is this? Line 1482 doesn't seem to match
up with my tree.
It sounds like either you're passing in parameters with the wrong type,
or it's a bug in the wrappers SWIG is generating, but it's hard to know
which without seeing your indexer code. The generated code looks OK to
me at least.
My best guess is that maybe you are passing a string for the weight
parameter in some case - as the documentation says:
One thing to be aware of though is that SWIG implements dispatch
functions for overloaded methods based on the types of the
parameters, so you can't always pass in a string containing a number
(e.g. "42") where a number is expected as you usually can in PHP.
You need to explicitly convert to the type required - e.g. use (int)
to convert to an integer, (string) to string, (double) to a floating
