+@subsection Problems With Character Sets
+
+If you try to use a character set that is not compiled into your binary,
+you can run into a couple of different problems:
+
+@itemize @bullet
+@item
+Your program has a wrong path to where the character sets are stored.
+(Default @file{/usr/local/mysql/share/mysql/charsets}).  
+This can be fixed by using the @code{--character-sets-dir}
+option to the program in question.
+@item
+The character set is a multi-byte-character set that can't be loaded
+dynamicly.  In this case you have to recompiled the program with the
+support for the character set.
+@item
+The character set is a dynamic character set, but you don't have a
+configure file for it.  In this case you should install the configure
+file for the character set from a new MySQL distribution.
+@item
+Your @file{Index} file doesn't contain the name for the character set.
+
+@example
+ERROR 1105: File '/usr/local/share/mysql/charsets/?.conf' not found
+(Errcode: 2)
+@end example
+
+In this case you should either get a new @code{Index} file or add
+by hand the name of any missing character sets.
+@end itemize
+
+For MyISAM tables, you can check the character set name and number for a
+table with @code{myisamchk -dvv table_name}.
