Bug Description

Request forwarded on behalf of George Brooke: http://www.markshuttleworth.com/archives/537#comment-336117

"And how about a circle of friends glyph somewhere (in the private use area if I understand what thats for correctly) could used as an easter egg in ubuntu-related websites maybe."

Ideally the Ubuntu Font Family would include a number of useful Free/open/libre software related labels where agreements can be made for their inclusion into the fonts *without impacting the DFSG freeness of the font*. The obvious ones are the:

  Ubuntu "Circle of Friends", Kubuntu Cogs, Xubuntu Mouse, Debian Swirl, Canonical Roundel, ...

The Ubuntu Font Family will hopefully see use not just in Ubuntu, but across the whole of Free Software (and maybe beyond): I hope that it will be possible to include as many libre-related easter-eggs as possible: from Ewing Penguins and Chameleons, to Fedora infinity-signs and magic stars on an equal basis. Like other expansions of the coverage outside of the initial five scripts, these will be up to the libre font community to contribute with any necessary background, research (and possibly agreements in place).

Simple geometric logos are generally not copyrightable, and trademarks are based on how something being used.

The new Kubuntu logo is, I believe, Copyright Roman Shtylman and distributed under a Creative Commons licence (as a derivative work of the new Ubuntu logo). As with other distro/vendor logos we would need to find a way of including these in the font that needed invoke the need for copyright assignment in all cases.

I don't have a problem with the use of the logo in the font. As I understand it the Creative Commons license allows such a use too? I never really thought about the fact that by creating it, copyright fell to me... I would be more than happy to assign copyright over to kubuntu/canonical as I have no need to hold it myself :)

Hello Roman, I could add you to the https://launchpad.net/~uff-contributors team and thus easily accept the Kubuntu logo as an addition, if you are able and willing to send a copyright assignment agreement (see instructions on that link).

(This would solve the issue for the Kubuntu logo, but not the generic inclusion of logos in general).

<sladen> do you now consider the Kubuntu logo Author: Existing + Roman Shtylman Copyright Holder: Canonical Ltd ?
<shtylman> yes.
<shtylman> I don't need to maintain copyright and it would make sense for canonical to have the copyright anyhow imho
<shtylman> I have already signed the [Canonical's contributor] agreement per my work with ubiquity

As this solves the issue for the Kubuntu cog, I've prepared and sent negative and positive EPS versions to Dalton Maag just now. And also added Roman explicilty to the contributors team.

Thanks Roman, glad to include your work in the font! Bet the Kubuntu
team will appreciate it too :-)

The 0.69 sources I have here have the logo, and additionally add a ligature table to inline-replace the string "![uU][bB][bB]" with the logo. As this sequence most likely already turns up in areas such as code (and needs to remain readable), I'm not totally confident about its merit. Thoughts, people?

Given !ubuntu is the name of a group used on identi.ca, and we feature a client (gwibber) which connects to that service, we may have a problem with the text "!ubu" being changed at runtime.

A small version of the Ubuntu Circle-of-Friends Roundel is at U+E0FF (geometrically aligned with where it appears in the logotype) but may have to move later. Other logos can be added when we aren't freeze critical.

nb. if we do want to add a ligature then it should be:

  "u,b,u,n,t,u,uniE0FF" → composite glyph with exact spacing/layout of the logotype.

this would mean that people can enter the sequence, but when they do it gets replaced with the exact logotype (which has closer tracking).

The "OpenLogos" font seems to be doing this more effectively that we can reasonably do here:

Per comment #9 and the request behind it; I've filed a bug for fixing the ligature insertion in a more reliable way over at bug #853855.
