Yes, you're right.

Generally, if in the expression "x % y" one of the values is StringType
and the other is UnicodeType, Python implicitly tries to convert the
StringType to UnicodeType. This breaks if the StringType contains
non-ASCII characters, because Python doesn't know which encoding these
non-ASCII characters are in.

The problem that you would have to know which variables hold StringType
values, and which variables hold UnicodeType values, to fix it properly.

_("foo %s") % bar  -> breaks if "bar" is UnicodeType
u_("foo %s") % bar -> breaks if "bar" is StringType containing non-ASCII

The only way of really properly fixing it is to go through *all* of the
code and change everything to use Unicode.

We already did this for appserver and for parts of common. But you need
knowledge of the underlying code to do that. So it will depend on the
forms/reports/etc. developers when this stuff will be fixed.

Meanwhile, we can't do much but fix those occurances of problems we
accidentally find.
