[TYPO3-english] Typoscript non-latin characters not saving

[David Cumberbeach]

I'm trying to setup a language selection menu with English and Korean. 
I'd like to render the "Korean" menu item/label in Korean (therefore not 
in latin characters).

So far though, when I paste the characters into the template setup, they 
appear to paste correctly, but when the template setup is re-opened the 
characters have not saved correctly and appear instead as question marks 
("???"). The menu item appears this way in the front end also.

Does TYPO3 support utf-8 or non-latin characters in typoscript?

Using TYPO3 4.7.12
I have the database character set & collation as UTF-8 unicode.
localconf.php has the following
$TYPO3_CONF_VARS['SYS']['setDBinit'] = 'SET NAMES utf8;'.chr(10).'SET 
SESSION character_set_server=utf8;';
$TYPO3_CONF_VARS['BE']['forceCharset'] = 'utf8';

Here's my language menu setup:
lib.langMenu = HMENU
lib.langMenu {
   special = language
   special.value = 0,1
   special.normalWhenNoLanguage = 0
     1 = TMENU
     1 {
       # Normal link to language that exists:
       NO = 1
       NO.allWrap = |*| | |*| |
       NO.linkWrap = <b> | </b>
       NO.stdWrap.setCurrent = English || ???
       NO.stdWrap.current = 1
       # Current language selected:
       ACT < .NO
       ACT.linkWrap = <b> | </b>
       # Language that is NOT available:
       USERDEF1 < .NO
       USERDEF1.linkWrap = <span> | </span>
       USERDEF1.doNotLinkIt = 1
     }
}

Thanks in advance,
