Project coordinating the encoding of medieval texts using the Private Use Area

In digital typography, the Medieval Unicode Font Initiative (MUFI) is a project which aims to coordinate the encoding and display of special characters in medieval texts written in the Latin alphabet or in runes, which are not otherwise encoded as part of Unicode.

MUFI was founded in July 2001 by a workgroup consisting of Odd Einar Haugen (Bergen), Alec McAllister (Leeds), and Tarrin Wills (Sydney). From 2006 to 2015, MUFI had a board of four members, consisting of the three founding members and Andreas Stötzner (Leipzig). Currently the board consists of Tarrin Wills, Copenhagen (Chair), Alex Speed Kjeldsen, Copenhagen (Deputy chair), Odd Einar Haugen, Bergen and Beeke Stegmann, Iceland.

In medieval texts, many special ligatures, scribal abbreviations, and letter forms existed, which are no longer a part of the Latin alphabet. As few of these characters are encoded in Unicode, ligatures have to be broken up into separate letters when digitized. Since few fonts support medieval ligatures or alternative letter forms, it is difficult to transmit them reliably in digital formats. To prevent the possibility of corruption of the source texts, the eventual goal of the MUFI is to create a consensus on which characters to encode, and then present a completed proposal to the Unicode Consortium. In the meantime, a part of the Private Use Area has been assigned for encoding, so these characters can be placed in typefaces for testing and to speed up the later transition to the final encodings (if the project is accepted). This was originally based upon work done by the TITUS project, which also deals with Greek, Cyrillic, Georgian, Arabic and Devanagari characters. As of Unicode 5.1, this proposal has been made, covering 152 characters, and most of these (89 in all) have been encoded in the Latin Extended D block. Others are in the Combining Diacritical Marks Supplement (26 chars. ), Latin Extended Additional (10 chars. ), Supplemental Punctuation (15 chars.) and Ancient Symbols (12 chars. ).

as of 2017, Junicode (GPL) is the first typeface to cover all of MUFI 4.0, also in its italic face. Prior to MUFI 4.0, there were some 39 code point conflicts with Junicode. The Kurinto Font Folio has two typefaces – Kurinto Book UFI and Kurinto Roma UFI – that cover all of MUFI as of 2020, including code points added after version 4.0 of MUFI. Kurinto also includes the code points of the CYFI and RUFI standards. There are three typefaces that are confirmed to cover all of MUFI 3.0. These are Cardo, Andron Scriptor Web and Palemonas MUFI. Only the last one comes in four faces (regular, italic, bold and both). LeedsUni supports all of MUFI 2.0. Caudex, which is available at Google Fonts for embedding, claims to support most of MUFI 3.0, but is not listed on the MUFI homepage. Alphabetum has an almost complete coverage of MUFI 2.0 and some coverage of version 3.0, in addition to a complete coverage of MUFI 1.0. TITUS Cyberbit covers all of MUFI 1.0 and includes some additional characters at different places, as it predates the MUFI project. There is a project to make available MUFI characters, including version 4.0 ones, in LaTeX.

Similar initiatives have been founded for Early Cyrillic Symbols (Cyrillic Font Initiative, CYFI) UNZ is a set compatible with MUFI, but it is not a true subset since it contains PUA additions of its own. It is intended for blackletter fonts, their typographic ligatures in particular. + LINCUA map of the BMP PUA U+ 0 1 2 3 4 5 6 7 8 9 A B C D E F E0 TITUS Latin capitals E1 E2 E3 E4 TITUS Latin lowercase E5 E6 E7 E8 TITUS Arabic MUFI medieval Latin E9 TITUS Devanagari EA TITUS Greek capitals MUFI Extension A EB TITUS Greek lowercase MUFI Extension B EC TITUS Georgian ED TITUS Extension A EE TITUS Extension A TITUS Cyrillic MUFI Ligatures A MUFI Enlarged minuscules EF TITUS Extension B CYFI Cyrillic A MUFI Ligatures B TITUS MUFI Misc.
