Installation

npm install printable-string --save

Usage

    var print = require(printable-string)
    console.log print("\x00 \t \v \u038b")     // -> \x00 \t \v \u038b
    console.log print("\x00 \t \v \u038b", {uppercase: true})     // -> \X00 \t \v \U038B

Prefix 0x will be used if the char code in ASCII range and the \u for the codes above 256.

Control codes will be converted to their literal expression as following:

    0x07 -> '\a'      // Bell
    0x08 -> '\b'      // Backspace
    0x09 -> '\t'      // Horizontal Tab
    0x0a -> '\n'      // Line feed
    0x0b -> '\v'      // Vertical Tab
    0x0c -> '\f'      // Form feed
    0x0c -> '\r'      // Carriage return
