Can I determine the length of a Unicode string (byte, codeunit, codepoint, grapheme or printing using the only proper font?)?.Can I compare Unicode strings for equality?.Can my Lua programs be written in Unicode?.Can I store, retrieve and concatenate Unicode strings?.Lua is unicode-agnostic and lua-strings are counted, so whenever you can treatunicode strings as simple byte sequences, you are done.Whenever that does not suffice, there are extension modules supplying your needs.You just have to figure out what exactly you mean by "support unicode" and use theproper abstraction from the right module. This is an attempt to answer the LuaFaq : Can I use unicode strings? or Does Lua support unicode?
