Russian media say Monotype Imaging, the U.S. company that owns several of the most popular fonts used on computers, has blocked access to its catalogue for users in Russia amid ongoing international sanctions on Moscow over its invasion of Ukraine.

The newspaper Vedomosti quoted IT sources as saying on April 14 that users in Russia were currently unable to get access to Monotypes’ fonts catalogue, meaning they cannot use popular fonts such as Times New Roman, Arial, Verdana, Tahoma, and Helvetica.

Monotype has not commented on the situation but when computer users inside Russia attempt to open a page to access the fonts, they receive a message saying, “The site owner may have set restrictions that prevent you from accessing the site.”

Lawyers and experts told Vedomosti that the access denial will not affect ordinary Internet users in Russia, but publishing houses and companies involved in producing computer software might be unable to use the fonts in the near future. The blockage can also be avoided by using a VPN.

Russian law allows so-called forced licensing to use products in the country even if the owners refuse to provide the country with licenses “due to the necessity to protect the interests of the state and society.”

In 2014, after Russia illegally annexed Ukraine’s Crimea region and threw its support behind separatists in eastern Ukraine, Monotype withdrew its permission to use its fonts in some Russian organizations, including IT companies that develop software programs for Russia’s Defense Ministry.

Times New Roman is a standard font for official documentation in Russia. In May 2016, Russian Communications Minister Nikolai Nikiforov called for the “cleaning” of documentation at official entities from foreign fonts.
