.SH NAME
ascii \- 在八進位制,十進位制,十六進位制中的 ASCII 字符集編碼
.SH 描述
ASCII 是美國對於資訊交換的標準程式碼。它是7位碼。
許多8位碼(比如 ISO 8859-1,
Linux 的預設字符集)容納 ASCII 作為它們的下半部分。對應的國際 ASSII 是 ISO 646。
.LP
下列的表格包含這 128 ASCII 字元.

.SH NOTES
.SS 歷史
在 AT&T UNIX 的 version 7 中出現過一份
.B ascii
手冊頁。
.LP
在一些舊的終端上,著重號(下劃線)用一個左箭頭顯示, 叫 backarrow ,
插入符作為一上箭頭被顯示並且垂直線在中間有一個洞。
.LP
大寫和小寫字元由僅在於一位的不同,還有ASCII字元 2 不同於雙引號也是一位。
這更加容易地為字元進行編碼,機械(鍵盤)或者是一個非微控制器基礎的電子鍵盤,
它們都能在舊的電傳打字機上找到配對。
.LP
ASCII 標準由美國標準協會(USASI)於1968出版.
.\"
.\" ASA was the American Standards Association and X3 was an ASA sectional
.\" committee on computers and data processing. Its name changed to
.\" American National Standards Committee X3 (ANSC-X3) and now it is known
.\" as Accredited Standards Committee X3 (ASC X3). It is accredited by ANSI
.\" and administered by ITI. The subcommittee X3.2 worked on coded
.\" character sets; the task group working on ASCII appears to have been
.\" designated X3.2.4. In 1966, ASA became the United States of America
.\" Standards Institute (USASI) and published ASCII in 1968. It became the
.\" American National Standards Institute (ANSI) in 1969 and is the
.\" U.S. member body of ISO; private and nonprofit.
