Yes, RAP can do that. But, as always, getting anything beyond US-=20
ASCII to work can be a serious pain.

It's all a question of getting the character encoding right. By =20
default, RAP assumes all data to be UTF-8 encoded. If your data is =20
not UTF-8 encoded, then you either have to convert it to UTF-8 =20
(recommended) or set DEFAULT_ENCODING in constants.php to the =20
encoding of your data (For the cyrillic alphabet, try "iso-8859-5" or =20=

"windows-1251").

Make sure that all your XML files start with an xml declaration (e.g. =20=

"<?xml version=3D"1.0" encoding=3D"UTF-8"?>", or whatever encoding =
you're =20
using instead of UTF-8). RAP-generated XML files will have this =20
automatically.

If you output HTML, make sure it has this inside the <title> element:
<meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3DUTF-8">
(or whatever encoding you're using instead of UTF-8). I'm not sure if =20=

all RAP-generated HTML has this.

RAP can't convert between different encodings, and can't combine RDF =20
input from different encodings. That's why I always recommend doing =20
everything in UTF-8. Most other encodings lack some characters that =20
some people will need.

If this doesn't help, could you please provide a more complete =20
example of what you're doing and where it doesn't work.

Yours,
Richard
