I was the one who packaged up extension-functions.tgz and posted on contrib. I didn't author the original code but I'd like to fix this up. I'm not clear on what needs to be changed. I gather that sqlite3utf8CharLen and sqlite3CreateFunc shouldn't be used. I'm not sure how to convert to use the external API. Anyone have a pointer?
Thanks.
