|No such thing as a small change|
Might be default some places (like on Ubuntu), but if using an X-display, will usually use Ubuntu-mono on the "X-server" (which is running on cygwin), Native Win, usually Lucida-Console, as native win doesn't have a decent renderer for X-fonts.
I normally do my editing/devel on *nix running "X" and displaying on a Win-console using cygwin-X.
So not really a "default" in either case (I chose "other"). I have tried several or most of the other fonts listed.
Important note:X running w/font-config doesn't use the same font to display all characters, so the question is slightly unanswerable if you use 'X' on modern *nix's. I.e. I'll get reasonable display of many languages (including Japanese), in-line along with interspersed English (cf. Win7-64native Vim -- have to use 1 font that has all the chars defined that I need), though such is not true in many win-native programs.
Ex. Using "SecureCRT" a tty-style ssh client for windows will display in-line Japanese in tty sessions:
*example can't be shown on non unicode accepting sites*
Why does this site display amber;pound(or sharp) and a number for UTF-8 input? Makes it hard to discuss what fonts look good or how they display when the site doesn't allow most of the world's characters... ;-(
