# cpmix64.htm

This application demonstrates mixing of text written in many European alphabets both in graphic and console window. Sample text is written in UTF-8 encoding here in this source file, no codepage switching is necessarry.

Sample text is displayed in a message box first using its default font.
Then is the same text displayed in console window which launched the application. Raster console font used as default in older Windows versions does not support glyphs for non-Latin characters, the text will be displayed correctly only if the user selects TrueType font in Properties/Font context menu of console window.
In Windows Vista and newer version can the current console font be selected by the program automatically.

> In MS-Windows XP and older the function SetCurrentConsoleFontEx is not available in kernel32.dll. Import of nonexisting function would make Windows to refuse launch of our application, that is why it tries to import the function indirectly, with LoadLibrary and GetProcAddress.
