ASCIIエンコード - 技術的な詳細

ASCII(American Standard Code for Information Interchange)は、128文字を持つ7ビット文字エンコード標準です。制御文字(0-31)、印刷可能文字(32-126)、DEL(127)を含みます。ASCIIはUnicodeとほとんどのテキストエンコードの基盤です。

コマンドラインでの代替方法

# Get ASCII value in terminal
printf '%d\n' "'A"  # 65
printf '%c\n' 65  # A

# Full ASCII table
man ascii
