DOCUMENT:Q111590 16-JUL-1999 [win16sdk] TITLE :BUG: Some TrueType Character Pairs Run Together on VGA PRODUCT :Microsoft Windows Software Development Kit PROD/VER:WINDOWS:3.1 OPER/SYS: KEYWORDS:kbOSWin310 _IK kbSDKWin16 ====================================================================== 3.10 WINDOWS kbprg kbbuglist ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Software Development Kit (SDK) 3.1 ------------------------------------------------------------------------------- SYMPTOMS ======== On some displays such as the standard VGA display that ships with Windows 3.1, certain TrueType font character pairs do not have any space between them and run together. For example, when using the Arial TrueType font at a point size of 14 or greater, the characters "f7" don't have any space between them. CAUSE ===== The standard VGA display driver does not support one-pass opaquing of the entire glyph black box so GDI must simulate. The simulation is not done correctly for certain characters. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. MORE INFORMATION ================ If you are using TextOut() to display the text and this slight cosmetic problem is not acceptable, you can use the ExtTextOut() function and specify the spacing between the characters.
