I recently posted a list of Chinese character variants and the Taiwanvore blogger posted an additional pair of variants to the list in the comments section – one in very common usage in Taiwan, specifically 裡 (for Cangjie fans that is 中田土) and 裏 (卜田土女). This variant pair is quite a rare example in modern Chinese as both are in regular usage, although according to Taiwan’s Ministry of Education, 裡 is the standard character (正體) and 裏 is the variant (異體).
