Hi Villu, I installed your recommended version of ICU4J 3.8 JAR in my classpath and it works very well on standard PDF files. Ligatures are resolved and diacritics are displayed correctly (although as combined characters) for files created with Acrobat Distiller. Files created with pdftex don't work as well: diacritical characters are completely lost (at least for my test file); with dvipdfmx I get "FRÉDÉRIC" correct, but also "D epartement de Math ematiques" for Département de Mathématiques" and "Z urich" for "Zürich" (the original is in small capitals, probably this creates problems). One file claiming to be created with "LaTeX with hyperref package" using "dvips + distiller" crashes: Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider
