naturally. Hence, the same hangul letter may be represented by different Roman letters, depending on its pronunciation in context. The Yale system, on the other hand, represents each Korean letter by always the same Roman letter(s) context-independently, thus not indicating the hangul letters' context-specific pronunciation. Even in texts that claim to follow one of the above, aberrations are a common occurrence and a major obstacle, e.g. when conducting an automated search on the Internet, as the searcher must check all possible spelling variants, a considerable list even without such aberrations. In addition to these systems, many people spell names or other words in an ad hoc manner, producing more variations (e.g. 이/리 (李), which is variously romanized as Lee, Yi, I, or Rhee). For more details, see Wikipedia:Naming conventions (Korean). SKATS is a transliteration system that does not attempt to use letters of a similar function in Western languages. A similar approach is to transliterate by hitting the keys that would produce a Korean word on a keyboard with Dubeolsik layout (e.g. 위키백과 → dnlzlqorrhk). This can often be seen on the internet, for example in usernames. Notes: Examples As a new writing system for Korean In the 1920s-1930s various languages of the Soviet Union were switched to the Latin alphabet and it was planned that the language of Koreans of the Far East would be one of them. Hanja was deemed too hard to learn, while Hangul was claimed to be inconvenient for typesetting and handwriting. Since removing of Hanja would result in much ambiguity, it was proposed that Chinese words would be replaced by words of Korean origin (compare linguistic purism in Korean). The new alphabet, made by famous Koreanist , who would later make a , looked like this: a ʙ d e æ g h i y k kh l r m n ng o ө ə p ph s t th u z Lowecase ʙ was commonly used in Soviet Roman-derived alphabets due to some alphabets having a letter similar to b with a different purpose. The usage of only lowercase letters was also not unusual, as it was the Latin alphabet of Adyghe language, for example. Some words written in the Soviet Latin alphabet: gu lli, nongdhion haggio, nong ʙ, zængsan, gugga diaʙondiyi. The alphabet saw criticism from Koreans and was never put into use.
