Jürgen,
I've seen similar messages (
com.tivoli.am.fim.fedmgr2.page.PageImpl E org.mozilla.javascript.EvaluatorException: illegal character: � (unnamed script#2)) in combination with .woff files not interpreted by AAC.
Based on the error stack, I suspect you might have some customized template files, with template scripting? (https://www.ibm.com/support/knowledgecenter/en/SSPREK_9.0.6/com.ibm.isam.doc/config/reference/template_file_scripting_aac.html)
Are these pages loading fine? (do you get any errors for loading font files - possibly browser plugin / developer tools can help identify this)
