+# With "language default" (=="latin9"), Babel strings come out wrong
+# when compiling with Xe/LuaTeX and TeX-fonts.
+# - The problem is generic to all Spanish documents but only manifests itself
+# if Babel strings with non-ASCII chars are actually used
+# (the ToC heading, e.g., becomes "ÃŊndice" instead of "Índice").
+# - In some cases, export fails
+# (see invertedTests, some more tests fail with TeXLive versions < 18).
+# Should we set inputenc to utf8 in the documents to work around the problem?
+# (Changing the default in lib/languages requires more tests for utf8 first.)
