Binary & Character Encoders

These encoders convert text to various numeric and binary representations.

bin

Aliases: bin-encode

Encodes text to 8-bit binary representation with spaces between bytes.

Usage

echo "abc" | eoyc -e "bin"
# Output: 01100001 01100010 01100011

How It Works

Each character is converted to its 8-bit binary representation:

• 'a' (97) → 01100001
• 'b' (98) → 01100010
• 'c' (99) → 01100011

Examples

echo "A" | eoyc -e "bin"
# Output: 01000001

echo "hello" | eoyc -e "bin"
# Output: 01101000 01100101 01101100 01101100 01101111

bin-decode

Decodes binary strings back to text.

Usage

echo "01100001 01100010 01100011" | eoyc -e "bin-decode"
# Output: abc

Examples

echo "01000001" | eoyc -e "bin-decode"
# Output: A

echo "01101000 01100101 01101100 01101100 01101111" | eoyc -e "bin-decode"
# Output: hello

oct

Aliases: oct-encode

Encodes text to octal (base 8) representation.

Usage

echo "abc" | eoyc -e "oct"
# Output: 141142143

How It Works

Each character is converted to its octal ASCII value:

• 'a' (97) → 141 (octal)
• 'b' (98) → 142 (octal)
• 'c' (99) → 143 (octal)

Examples

echo "A" | eoyc -e "oct"
# Output: 101

echo "hello" | eoyc -e "oct"
# Output: 150145154154157

oct-decode

Decodes octal strings back to text.

Usage

echo "141142143" | eoyc -e "oct-decode"
# Output: abc

Examples

echo "101" | eoyc -e "oct-decode"
# Output: A

echo "150145154154157" | eoyc -e "oct-decode"
# Output: hello

unicode

Aliases: unicode-encode

Encodes text to Unicode escape sequences in the format \uXXXX.

Usage

echo "hello" | eoyc -e "unicode"
# Output: \u0068\u0065\u006c\u006c\u006f

Examples

echo "A" | eoyc -e "unicode"
# Output: \u0041

echo "@" | eoyc -e "unicode"
# Output: \u0040

echo "abc" | eoyc -e "unicode"
# Output: \u0061\u0062\u0063

Use Cases

• JavaScript/JSON string escaping
• Unicode character representation
• Cross-platform text encoding

unicode-decode

Decodes Unicode escape sequences back to text.

Usage

echo "\\u0068\\u0065\\u006c\\u006c\\u006f" | eoyc -e "unicode-decode"
# Output: hello

Note: The backslashes need to be escaped in shell.

Examples

echo "\\u0041" | eoyc -e "unicode-decode"
# Output: A

echo "\\u0061\\u0062\\u0063" | eoyc -e "unicode-decode"
# Output: abc

charcode

Aliases: charcode-encode

Encodes text to decimal ASCII/character code values separated by spaces.

Usage

echo "abc" | eoyc -e "charcode"
# Output: 97 98 99

How It Works

Each character is converted to its decimal ASCII value:

• 'a' → 97
• 'b' → 98
• 'c' → 99

Examples

echo "A" | eoyc -e "charcode"
# Output: 65

echo "hello" | eoyc -e "charcode"
# Output: 104 101 108 108 111

echo "123" | eoyc -e "charcode"
# Output: 49 50 51

charcode-decode

Decodes character code values back to text.

Usage

echo "97 98 99" | eoyc -e "charcode-decode"
# Output: abc

Examples

echo "65" | eoyc -e "charcode-decode"
# Output: A

echo "104 101 108 108 111" | eoyc -e "charcode-decode"
# Output: hello

Round-Trip Examples

All encoding/decoding pairs support round-trip conversion:

# Binary
echo "test" | eoyc -e "bin" | eoyc -e "bin-decode"
# Output: test

# Octal
echo "test" | eoyc -e "oct" | eoyc -e "oct-decode"
# Output: test

# Unicode
echo "test" | eoyc -e "unicode" | eoyc -e "unicode-decode"
# Output: test

# Character codes
echo "test" | eoyc -e "charcode" | eoyc -e "charcode-decode"
# Output: test
