+# * Encoding is the default encoding used with TeX fonts.

+# * InternalEncoding is used to tell LyX that babel internally sets a

+# If True, LyX cares for characters/macros that do not exist in
+# some font encodings ("<", ">", "|" and straight quote).
+# It is not required for standard encodings like T2A. See bug #5091.
