This is the list of Hangul "jamo" (Korean alphabet letters which represent consonants and vowels in Korean) including obsolete ones. This list contains Unicode code points.
In the lists below,
The Hangul compatibility jamo characters (codice_9–codice_10) are encoded in Unicode for compatibility with the earlier South Korean national standard KS X 1001 (formerly KS C 5601). Compatibility and halfwidth (codice_11–codice_12) characters are not composable into syllabic squares (because of the ambiguity for delimiting syllables when using them), but they may be used in legacy applications which cannot support or render the full Hangul syllable set such as low-cost terminals or old printers: these compatibility characters may exist either in fullwidth variant, or in halfwidth variants (mostly used in terminals with low resolution).
Unicode also defines a large subset of precomposed Hangul syllables (codice_1–codice_2) made of two or three jamo characters for use in modern Korean (their canonical decomposition mappings are "not" found in the UCD, but are specified with an arithmetic algorithm only in "The Unicode Standard", Chapter 3 "Conformance") and are decomposable into equivalent sequences of two jamo characters (one in each of the first two subranges above) or three jamo characters (one in each of the three subranges above). Their initial encoding in Unicode 1.0 was different (and not compatible with later versions of Unicode) and were based on the compatibility jamo characters (ignoring the distinction between leading and trailing consonants, making the automatic composition of Hangul square sometimes ambiguous or wrong).
Other characters.
These are not "jamos", but are used in combination with other Hangul jamo characters and syllables.
