As Petite mentioned, you can include any > 0x7F character in a single-byte Lua string unescaped (which includes the bytes of all extended characters in UTF-8). If you want to escape Unicode characters, how depends on what byte encoding you want the character to be in. If you're using UTF-8 (generally the most sensible choice), you can include U+2500 as \226\148\128 (or \xe2\x94\x80 in 5.2).
Stuart,thanks for your long answer. Yes, I'm using UTF-8 on my system, so the whole thing isn't a real problem. I can always open a UTF-8 table in a browser, copy the character I'm interested in, switch back to the editor window, and paste it into my source. But I would rather avoid this tedious procedure. Bash, for example, allows the notation \uxxxx, which is very convenient. However, the octal notation you mention is OK as well (I didn't realise that the unicode tables in http://www.utf8-chartable.de can be switched from hex to octal).
