We'd like to use Raleway on our PCs but the numerals are by default jittered. The description says it's achievable to get the lining versions that are all horizontally aligned.
I've found this SO question that details how to get the lining version via CSS but does anyone know how to get it in a download?
You can use the Expert mode on http://www.fontsquirrel.com/tools/webfont-generator with OpenType flattening to generate a new font with lining numerals turned on.
Additionally, you could generate a font with the stylistic alts. This will give you a more modern, alternative W.
Like turning on/off any other OpenType feature, you tell the application that you're using the font in to enable lining. If your application does not offer that control, either get a better application, or do the decent thing and get in touch with https://www.theleagueofmoveabletype.com, as they're people who actually make Raleway (which really should have been your first stop =) Just because it's a webfont doesn't mean you're automatically free to alsu use it on your desktop, although in this case, TLoMT allows that.
