 The extended katakana are based on regular katakana and either are smaller in size or have a handakuten.As few fonts yet support these extensions, workarounds exist for many of the characters, such as using a smaller font with the regular katakana ク "ku" to produce ク to represent the separate small katakana glyph "ku" used as in ("Aynu itak").This is a list of special katakana used in transcribing the Ainu language.
