Note: the first version of the font .deb made available to Ubuntu Members on 2010-07-07 accidentally contained 'nda' in the package name. This was immediately fixed within twenty-four hours. A non-disclosure agreement (NDA) is not required to test the Ubuntu Font Family.

Howto

On 2010-09-28, the libre-licensed version of the ttf-ubuntu-font-family package was added to the seed lists and the meta packages for the Ubuntu 10.10 release candidate. If you are running, testing, or installing "maverick" the the package will already be on your machine, if not, run "update-manager" to install it. No themes currently use the font as default, yet.

As of 2010-08-20 the font is still in a phased beta, if you have are a member of the many Launchpad groups with access (eg. ubuntu-members), you should be able to:

  1. Visit https://launchpad.net/people/+me/+archivesubscriptions

  2. Click View next to ubuntu-font-beta-testing

  3. Add the personalised archive details to your machine's /etc/apt/sources.list

  4. sudo apt-get update

  5. sudo apt-get install ubuntu-private-fonts

If you are not yet a member of any team, but have an interest in typography (and a genuine willingness to provide feedback during development) or you are working on marketing or screenshot materials, please first:

  1. Go to the ubuntu-typeface-interest team in Launchpad

  2. Click Join the team on the right-hand side

This allows a wider-range of people gain access to the font family packages without risk of disrupting the work of existing Launchpad teams focused on other topics (eg. Accessibility/Kubuntu) or affecting their quorum by stacking the teams with memberships purely to gain development access to the font family.

Please do not try to download just the .deb or .tar.gz on its own; the test fonts change weekly (normally on a Monday) and having old copies of broken/superceded versions is producing incorrect bug reports. Even worse documents are ending up with the out-of-date fonts embedded in them. Changes of glyph metrics during the beta test will later cause documents to reflow unexpectedly if they've changed! So, please stick to the personalised PPA!).

(BTW, this process is only for the testing phase! Life will be much easier after release and things have settled down). If you are seening verification errors from the package archive, run the following to import the PPA-specific signing key:

  • sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 42F834EC

Timeline

aa As of August 2010, development is on-going and continuous. Snapshots are being gradually rolled out on a phased basis, to wider circles of people, and in larger snapshots as the opportunity of each six-monthly Ubuntu release approaches:

  • Ubuntu 10.04: very early snapshot used for the 2010 X/K/Ubuntu re-branding exercise

  • Ubuntu 10.10: Should have four fonts in sans-serif style: Regular, Italic, Bold, Bold Italic

  • Ubuntu 11.04: Additional fonts, and expanded language coverage, including Monospace for terminal use!

Like all software destined for the Ubuntu main repository, the Ubuntu Font Family will be under a completely Free/open licence before it gets added!

Phased beta

The initial Alpha and Beta testing of the Ubuntu Font Family has been rolled out in phases under progressively more open distribution conditions:

  • Canonical design team ("DX"), proprietary, NDAed, Sup3r S3cr3t (later 2009)
  • Canonical employees, proprietary, NDAed (early 2010)
  • Ubuntu members + web-preview, proprietary (July 2010)
  • more to come!...

The font family is a long-term project and the phased feedback process is not something that everyone has immediately embraced! It is however a historical development: Dave Crossland (of the Open Font Library) notes on the LWN article that this the first time that a traditional proprietary font foundry company has been prepared to release any beta test versions of their in-development fonts. Non-profit foundries have released design reviews and public betas. Hopefully in the future the Ubuntu Font Family can be held up as an example of success and open up the possibilities to go even further. Lets make this work!

From a font-designer's point-of-view, half-finished fonts have had the unfortunate habit of getting distributed and spreading the wild ("like viruses"). Mainstream use of incompatible revisions of a typeface cause issues such people's documents re-flowing where characters or metrics are refined between the earlier and the final versions.

Technology

  • OpenType-based TTF (TrueType)

  • Alternative glyphs (eg. proportional/non-proportional/superscript/subscript numerals)
  • Debugging glyphs (U+EFFD, U+EFFE, U+EFFF, U+F000) giving face, version, grayscale level and pixels-per-em digit display)

The pixels-per-em 7-segment digits are driven by the hint engine (substituted from the Deja fonts), so if hinting is by default off (eg. Firefox) then the output will show as a pair of '88' numerals.

For some idea of what OpenType alternatives allows, see the following video of Firefox developments in progress:

Design process

noHO The four Latin characters, 'n o H O' helped to define a guide for around 80-percent of the remaining characters.

Extensive manual hinting has been performed for rendered sizes below 60 pixels-per-em.

Software tools

Dalton Maag are using the following tools:

  • Fontlab Studio

  • Microsoft Visual Truetype (VTT)
  • In-house Python-based accent placement scripts

In Ubuntu:

  • Gucharmap (Applications->Accessories->Character Map)

  • fontmatrix (apt-get install fontmatrix)

  • FontForge (apt-get install fontforge)

  • open font design toolkit (apt-get install open-font-design-toolkit)

FontForge (as of mid-2010) does not handle some extended OpenType features, hopefully having a libre/open font that uses these features will speed development in being able to support the them!

FAQ

Frequently faked questions:

  • Q: Will Kubuntu switch to the Ubuntu Regular font for the desktop interface? A: The Kubuntu community will consider it when the font family is in the archive (eg. finalised in form and licence).
