《编辑学报》先后有三篇短文说“○”。这些短文的要旨,归纳起来,实际上包含两个相关但并不相同的问题:其一,对应于阿拉伯数字“0”,中文出版物上如用汉文数码标记,可否写作“○”。这个问题是关于“○”的功用,即它存在和应用的价值。其二,“○”是否属于汉字。这个问题是关于“○”的身分及其在汉语辞书中的地位。 “Editorial” has three essays that “○.” The essence of these essays, in summary, actually contains two related but not identical problems: First, corresponding to the Arabic numeral “0”, the Chinese publication can be written as “○” if it is marked with a Chinese numeral. This question is about the function of “○”, that is, its value of existence and application. Second, “○” belongs to the Chinese characters. This question is about the “○” status and its status in Chinese dictionaries.
