Reforms of Russian orthography
Russian orthography has been reformed officially and unofficially by changing the Russian alphabet over the course of the history of the Russian language. Several important reforms happened in the 18th–20th centuries.
In early Russian typewriters like this one, there was no key for the digit 1, so the dotted І was used instead. Following the Russian alphabet reform of 1918, a 1 key was added.

The Russian alphabet is the script used to write the Russian language. It comes from the Cyrillic script, which was devised in the 9th century for the first Slavic literary language, Old Slavonic. Initially an old variant of the Bulgarian alphabet, it became used in the Kievan Rusʹ since the 10th century to write what would become the modern Russian language.
