ASCII table

The ASCII (American Standard Code for Information Interchange) table specifies the characters (column c of the table below) associated with the numbers 0 to 127 (Unicode numbers U+0000 to U+007F). The set of all the characters in the table constitutes the ASCII alphabet.

Bảng ASCII (American Standard Code for Information Interchange) chỉ định các ký tự (cột c của bảng bên dưới) được liên kết với các số từ 0 đến 127 (số Unicode U+0000 đến U+007F). Tập hợp tất cả các ký tự trong bảng tạo thành bảng chữ cái ASCII.
