International Latin Alphabet 2016

The Unified Latin Alphabet, version 2016 applies the following rules:

1. 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
2. Character - sound correspondence
   1. a, e, i, o, u, y 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/ and q = /ʒ/ have the value as in IPA.
