數學字母數字符號
Unicode碼位區段
數學字母數字符號(Mathematical Alphanumeric Symbols)是Unicode的一個碼位區段(Unicode block)的正式名稱。包含不同字型風格的拉丁字母、希臘字母與十進制數字在數學中用作不同指代含義的符號。例如,黑板粗體(blackboard bold),Unicode中使用的對應術語是雙線體(double-struck)。

Unicode的第一輔助平面的碼位區段1D000-1DFFF是「記號系統」(Notational systems),在U+1D400
... U+1D7FF
包含了稱之為數學字母數字符號的字形). 這使得可以專門設計與使用特殊的數學字符字型,不同於正文中使用的普通字母、數字。例如,數學中使用的斜體 "A"與正體字母"A"有不同的含義. 這些數學字母數字符號僅用於數學公式,不用於普通的文本中.
不同字型的這些符號在不同的數學領域往往具有特定的、固定的含義。
列表
十六進制數字表示其下的字符的Unicode碼位。其它字符的碼位沿著列向向下依次增加。具有粉紅色背景的字符實際上是在其它Unicode碼位區段,例如ℛ (script capital r)的碼位是U+211B,在基本多文種平面.
還有一種情況,例如U+1D4C1: 𝓁(mathematical script small l),還有一個類似外觀的字符U+2113: ℓ (script small l).[3]
