24 March 2015 – Universal Acceptance Steering Group Publishes Charter
The Universal Acceptance Steering Group Charter is now available for review. Learn about the UASG's mission, scope, goals and more.
10 February 2015 – Universal Acceptance Initiative Ramps Up at ICANN 52
Christian Dawson addresses the ICANN Board: "The ICANN community should support the creation of a steering group to guide the identification of top line issues and propose solutions, as well as the creation and dissemination of best practices and general outreach information about Universal Acceptance."

In the earliest days of the Internet, the Domain Name System (DNS) contained a small set of Top-Level Domains (TLDs), such as .com, .net and .org, which were named in the ASCII character set containing two or three A-Z letters. Early applications and service user interfaces were based on these assumptions remaining the same, and worked to help and protect Internet users by allowing only "known" TLDs to be used.
Universal Acceptance refers to the occurrence of users experiencing browser and email bugs when trying to use new gTLDs. Operators of new gTLDs and more visibly all IDN TLDs (gTLDs and ccTLDs) are seeing unnaturally limited demand for names in the zones and this has presented a challenge to the goals of the new gTLD program of user choice, user confidence and name space competition.
Domain names in a TLD must be useable in applications regardless of the written script, length or newness of the TLD. The four main shifts spurring the need for Universal Acceptance:
Longer TLD Names: TLDs with names longer than four characters, such as MUSEUM.
Non-Latin based TLDs: Resulting from the addition of TLD names written in scripts other than ASCII, such as Cyrillic, Arabic and Chinese.
Rapid addition of TLDs: The New gTLD Program is spurring very rapid additions of long ASCII names and IDN names – as of 15 August 2014, there were 1,326 applications currently proceeding through the New gTLD Program.
International Email: The introduction of non-ASCII names in email. While International Domain Names (IDNs) solved part of the ability to have non-ASCII names for servers, it doesn't solve the ability to have non-ASCII names for mailboxes.
As the Internet evolved to be more personal, targeted and global, these assumptions are no longer valid. But limitations based on the old assumptions linger and now are preventing a larger and ever growing group of users from accessing the entire expanse of the Internet. In some instances, Internet users trying to use the newly delegated generic Top Level Domain (gTLDs), whose names may be many characters long and/or in non-Latin scripts, can experience "bugs" or the inability to access/register the sites.
This problem must be solved, and Universal Acceptance realized, in order to achieve a truly global, scalable Internet. It will be considered complete when any person can register and use a domain name in any top-level domain in widely distributed web browsers, email clients, in setting up accounts for Internet services and other services.

ICANN has established a roadmap charting its involvement in achieving Universal Acceptance, see the Universal Acceptance Initiative Roadmap.

Background: How did we get where we are today?
- Introduction of "com/net/org" and the ISO 3166 two letter codes
- Introduction of email addresses (mailbox names) were ASCII
- Assumptions were made, "burned in". User interfaces would list valid TLDs and security rules were built according to this list.
- Expansion approved in 2000 and again in 2003 Broke assumptions about Valid TLDs re: name length (already have these dates, obviously)
- Expansion into IDN ccTLDs, broke assumptions re: ASCII in TLD names
- Hundreds of New gTLDs proposed, Broke assumptions of "no/few changes" to root
- Email names extended from ASCII to UTF8, Broke assumptions in email systems and viewers
- The first IDN ccTLDs appeared in May 2010.
- The delegations of the 2012 round of so-called new gTLDs started in Fall (October) 2013 and continues, they were "proposed" in 2012. (You know the story.) But refrain from being very specific; keep this info graphic as a cartoon, so as not to drawn attention to the fuzziness of the history.
