Hi Sebastian, thanks for the link to the article on i18n of semantic web apps, any resource about i18n is greatly appreciated since it is generally regarded as a "less-important-than-other-things" issue.

About UTF-8 ordering, I was refering to collations RDBMS like MySQL tend to use with UTF-8: http://dev.mysql.com/doc/refman/5.1/en/charset-unicode-sets.html http://www.collation-charts.org/mysql60/mysql604.utf8_general_ci.european.html But after all it seems there is a defined "stardard" order or collation for UTF-8: http://www.unicode.org/reports/tr10/ > Did you try it on other stores or Jena? I didn't try the query on other stores or Jena, so I can't tell if there is any difference. I'll post findings when I do.
