+The ligatures \enquote{\ij} and \enquote{\IJ}, as used in Dutch,
+are only available in most \TeX{} fonts, if the commands \cs{ij} or
+\cs{IJ} are used or when you enter them as UTF-8 characters U+0133 or

+\cs{MakeLowercase} would always fail regardless of the input method.
+This has now been corrected.
