Universal Acceptance (UA) is a term coined by Ram Mohan to represent the principle that every top-level domain (TLD) should function within all applications regardless of script, number of characters, or how new it is.
ICANN began to address these issues through initiatives such as creating a Universal Acceptance Toolkit[2] in 2006, which provided reference code to software developers on how to cater for all TLDs correctly.
For this reason, the UASG commissioned a report on the performance of major browsers in the treatment and acceptance of 17 different domain names registered for the purpose of providing test cases for UA readiness.
Common problems among the other browsers included the failure to properly render the URLs in the tab title bar and failing to treat an ideographic full stop as a delimiter.
On mobile platforms, the results of the tests were much more varied, with the same browsers performing differently based on the operating system, with one of the most common problems being the proper display of Unicode URLs.
Internationalized Domain Names (IDNs) are linked to Universal Acceptance, because TLDs in local languages are always more than 3 letters long, and often do not work well in browsers, emails and other internet applications.
While these allegations were not investigated, the current leadership has been viewed as opposed transparency and openness measures, including the publication of a Statement of Interest of each UASG member.
