International Latin Alphabet 2015

Rules

The Unified Latin Alphabet applies the following rules:

Character inventory
1. Use only characters from ISO 8859-1.
  1. prefer 65-90, (A-Z) and 97-122 (a-z), i.e. ISO 646
  2. from the others, prefer for vowels those that are present in several other ISO 8859 standards, i.e. characters with acute, grave, circumflex or diaeresis
Character - sound correspondence
1. a, e, i, o, u with or without diacritics represent vowels.
2. j and w represent semivowels as in IPA
3. the rest represent consonants
  1. In the ULA-base form all characters except for c = /ʃ/, q = /ç/ and y = /ʒ/ have the value as in IPA.

/j/
- Serbian, Croat, Czech: j, e.g. Jakovo
- Bulgarian (official Romanization): y, e.g. Yakovo (bulg.: "unnecessary" divergence from IPA)
- ULA: j
/ts/
- Serbian, Croat, Czech: c, e.g. Gorica
- Bulgarian (official Romanization): ts, e.g. Goritsa (bulg.: more logical, since t and s exist already)
- ULA: ts
