+# SYNOPSIS
+#
+# TUKLIB_MBSTR
+#
+# DESCRIPTION
+#
+# Check if multibyte and wide character functionality is available
+# for use by tuklib_mbstr_* functions. If not enough multibyte string
+# support is available in the C library, the functions keep working
+# with the assumption that all strings are a in single-byte character
+# set without combining characters, e.g. US-ASCII or ISO-8859-*.
+#
+# This .m4 file and tuklib_mbstr.h are common to all tuklib_mbstr_*
+# functions, but each function is put into a separate .c file so
+# that it is possible to pick only what is strictly needed.
