The 200 range is mostly retired IPA consonants, though it includes several letters of the
Americanist Phonetic Alphabet that are sometimes used alongside the IPA. A few superscript IPA letters, including a single vowel, have also been assigned numbers in this range. Symbols official until retirement by Kiel in 1989 are numbered upwards from 201; those already retired, or not IPA at all, are numbered downwards from 299. In addition, there is the pre-composed character , the loop-tail (see the main consonant chart above), and the implicit IPA letter . ==300: IPA vowels==
