-WHAT IS THIS?
-
-This is ProFont TrueType, converted to Windows TrueType format
-by Mike Smith, with some tweaks added by "ardu".
-
-Modifications include:
-- A Euro character
-- Missing characters from the Latin 1 code page
-- Full support for CodePage 850. These are mostly the famous
-  block/box characters you know from DOS. Very useful if you use
-  Mightnight Commander through PuTTY.
-- Fixed metrics so that point size of 9 works correctly. Until now
-  you had to select 7 to obtain the native point size of 9.
-- Added some quick&dirty hinting for point size of 9. Most characters
-  now match closely the look of the bitmap version.
-  Don't expect it to look good on anything else than Windows...
-
-

-and more information
