Ș

The letter was proposed in the Buda Lexicon, a book published in 1825, which included two texts by Petru Maior, Orthographia romana sive latino-valachica una cum clavi and Dialogu pentru inceputul limbei române, introducing ș for /ʃ/ and ț for /ts/.

In some contexts, like with low-resolution screens and printouts, the visual distinction between ș and ş is minimal.

In 1999, at the request of the Romanian Standardization Association [ro][citation needed], S-comma was introduced in Unicode 3.0.

Nevertheless, encoding for the S-comma was not supported in retail versions of Microsoft Windows XP, but a later European Union Expansion Font Update provided the feature.

While digital accessibility to S-comma has since improved, both characters continue to be used interchangeably in various contexts like publishing.

S with "half moon" beneath (" s subnotamus signo mediae lunulae") proposed as a letter in the Buda Lexicon. Note that the form is reversed from the modern version, resembling a small C.
