𱁬（，日语发音可作、或等）是一个日本和制汉字，以其84划的总笔画数使之成为目前图形上最复杂的CJK文字。这个罕见而复杂的汉字将36画的汉字“䨺”（三重“云”，意为多云）以图形叠加的方式置于48画的“龘”（三重“龙”，意即龙腾飞的样子）之上。除该字之外第二复杂的CJK汉字是58画的汉字“𰻞”（biáng，），后者用于指代一种流行于陕西关中地区的油潑扯麵。

字源
组成“”字的上下汉字结构均为会意字，其上半部分由多個12划的汉字“”組成，視異體字不同可三重叠加為36画的“䨺”（中文發音作“-{zh-cn:duì;zh-tw:ㄉㄨㄟˋ}-”，意為多雲）或四重叠加為48画的“𩇔”（中文發音作“-{zh-cn:nóng;zh-tw:ㄋㄨㄥˊ}-”，意為大範圍多雲）；而下半部分則由16划的汉字“”重叠組成，既可雙重叠加為32畫的“龖”或三重叠加為48畫的“龘”（均讀作“-{zh-cn:dà;zh-tw:ㄉㄚˋ}-”，意為龙飞翔的模樣，兩字為異體字關係），也可四重叠加為64畫的“𪚥”（中文發音作“-{zh-cn:zhé;zh-tw:ㄓㄜˊ}-”，為“讋”的異體字，意為喋喋不休或多嘴）。

該字最常見的有两种異體字（见右圖），二者主要的区别在于第一个“龙”字的位置。 在異體字1（读作“daito”或“otodo”）中，第一個龙字写在第二个和第三个云字之间，从第25划起开始寫；在異體字2（读作“taito”）中，第一個龙字写在第三个云字之下，从第37划起开始寫。

用途
一些專業的日语词典當中可能會收錄該字符。Ono 和 Fujita (1977) 的读音困难的日本人名词典中收錄了发音为daito或otodo的異體字1。而Ōsuga (1964) 的姓氏词典以及 Sugaware 和 Hida (1990) 的國字词典中則包含了发音为taito的变体字2。

这个由84畫漢字書寫的死語于2000年在現實中被真正采納為名字，当时千叶县北松户站附近的一家拉面店使用发音为Otodo的变体字1命名（Sasahara 2001）。

中文词典 

Unabridged dictionaries of Chinese characters do not include either Japanese 84-stroke taito variant. Both Morohashi Tetsuji's Chinese-Japanese Dai Kan-Wa jiten, which has 49,964 head entries for characters, and the Chinese Hanyu Da Zidian (1989), which has 54,678, list the three most graphically complex characters as the 52-stroke Japanese hō or bō and Chinese bèng 䨻 "sound of thunder" (with quadruple 雷 "thunder"; 1960: 12693, 1989 6: 4085), 64-stroke tetsu or techi and zhé 𪚥 "chatter; be garrulous" (with quadruple 龍 "dragon"; 13747, 7: 4806), and 64-stroke sei and zhéng 𠔻 "meaning unknown" (with quadruple 興 "rise"; 9816, 1: 254)—the first occurrence of the ghost word 𠔻 was in Sima Guang's (1066) Leipian dictionary, which gives the pronunciation gloss zhèng 政 but no semantic gloss.

编码 

Some extensive encoding systems for Japanese kanji (preceding Unicode) include taito variant character 2. The superseded Mojikyo font, which comprised 142,228 rare and obsolete characters, included it as number [066147]. The deprecated BTRON Business computer architecture TRON project (TRON stands for "The Real-time Operating system Nucleus") also included taito [3-7D6B], and it was included in the font under development by the Tokyo University of Foreign Studies's Jitī shotai GT書体 project.

In December 2015 it was included in document IRGN2107 as one of 1,640 characters submitted to the Ideographic Rapporteur Group for encoding in Unicode (character source reference UTC-02960).  The character was provisionally included in "IRG Working Set 2015", which are candidates for inclusion in a future CJK Unified Ideographs extension.

This character was added to Unicode version 13.0 in March 2020. The character is located at U+3106C (𱁬) in the CJK Unified Ideographs Extension G block in the newly-allocated Tertiary Ideographic Plane.
