Reproduction
 0. Start any application, e.g. Writer.
 1. Tools - Options - Language Settings - Languages.
 2. Turn on each option labeled "Enabled for Asian languages" and 
    "Enabled for complex text layout (CTL)"
 3. Format - Character - Font
 4. Confirm a message (A) is displayed at the bottom of the dialog.
 5. Type invalid font name in the font name field for Western text font.
    Confirm that the message (A) is now replaced with (B).
 6. Click on a rectangle mark at the right end of font name field for Asian text 
    font and choose an available font that has been installed in your computer.
 7. You may expect that the message should be changed from (B) to (A).
    In reality, nothing happens for Asian text font.

 (A) "The same font will be used on both your printer and your screen."
 (B) "This font has not been installed. The closest available font will be used."

Expectations
 In the dialog, each script, Western, Asian, and CTL, has four controls: 
 Font, Typeface, Size, and Language. 
 When a user click on one of the controls, the message should be properly 
 shown depending on what script is currently focused on. 

Background
 I believe this phenomenon has been known for years. Please reconsider the 
 situation where you choose a correct font installed in your computer, but 
 the OpenOffice.org states that the font you have chosen is not installed 
 in your system. There are obviously something that can be improved.
