+By default, you will be offered a choice from all the fixed-width
+fonts installed on the system, since VT100-style terminal handling
+expects a fixed-width font. If you tick the box marked \q{Allow
+selection of variable-pitch fonts}, however, PuTTY will offer
+variable-width fonts as well: if you select one of these, the font
+will be coerced into fixed-size character cells, which will probably
+not look very good (but can work OK with some fonts).
