Another bit of good news is that these three expanded DejaVu font sets each include a glyph for the ʻokina U+02BB. http://en.wikipedia.org/wiki/%CA%BBOkina http://www.dejavu-fonts.org/wiki/PDF_samples This is important for some languages of Oceania (Tongan and Samoan). I've managed to get a Samoan L10n effort started and knowing that the ʻokina glyph will be properly presented is reassuring. cjl ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I made a half-hearted attempt at pushing for this in 12.1.0 cycle, and dropped the ball halfway. This will increase the base uncompressed OS size by about 6mb.

Re: Shipping bigger fonts by default for greater glyph coverage
Something to watch out for is the content of /usr/lib/locale. Having been caught several time in the past with C as the only language recognized, I now pay attention to the content of that directory. [For instance, allowing a Fedora upgrade of the package 'glibc-common' could add an extra 80 MB into that directory. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I tend to view stock OLPC releases as the car you drive when you are shopping. Sure you could drive it off the lot as-is, but if you are really picky about the options packages (e.g. fonts and that 6 MB) you are going to wait for a custom ordered car from the factory (an OS Builder custom build). It is a very good thing if the OLPC stock releases be flexible enough to accommodate additional languages by just dropping in the right language pack. This makes them ideal technology demonstrators for assessment (with L10n and on locked XO laptops) before deciding to invest additional effort in a custom build and for many, just adding the language pack will be good enough (with the larger set of glyphs). This reminds me that I need to fiddle with the langpack generating script on Pootle so that we are cranking out 0.96 based langpacks going forward. cjl ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Shipping bigger fonts by default for greater glyph coverage
IIRC its only the CJK fonts which really bloat the build. There's an old bug in trac which discussed fonts at length; it might be worth digging that up to ensure we're still covering all the languages we were covering then. --scott On Sep 5, 2012 6:58 PM, Chris Leonard cjlhomeaddr...@gmail.com wrote: On Wed, Sep 5, 2012 at 6:58 PM, Mikus Grinbergs mi...@bga.com wrote: Something to watch out for is the content of /usr/lib/locale.
