Install

Install using npm:

$ npm install --save node-native2ascii

You'll need to have at least Node.js 8 or newer.

If you want to use the command line interface you'll most likely want to install it globally so that you can run native2ascii from anywhere:

$ npm install --global node-native2ascii

CLI

Usage: native2ascii [options] [inputfile] [outputfile]


Options:

  -e, --encoding <encoding>  specify encoding to be used by the conversion procedure
  -r, --reverse              perform reverse operation
  -V, --version              output the version number
  -h, --help                 output usage information

Converts a file that is encoded to any character encoding that is supported by Node.js (which can be controlled via the encoding command line option and defaults to utf8) to a file encoded in ASCII, using Unicode escapes ("\uxxxx" notation) for all characters that are not part of the ASCII character set.

This command is useful for properties files containing characters not in ISO-8859-1 character sets.

A reverse conversion can be performed by passing the reverse command line option.

If the outputfile command line argument is omitted, standard output is used for output. If, in addition, the inputfile command line argument is omitted, standard input is used for input.

Examples

Converts a UTF-8 encoded file into an file encoding in ASCII, Unicode escaping characters not in the ASCII character set:

# Using file command line arguments:
$ native2ascii utf8.properties ascii.properties
# Using STDIN and STDOUT:
$ cat utf8.properties | native2ascii > ascii.properties

Converts a ASCII encoded file into a file encoded in UTF-8, unescaping any Unicode escapes:

# Using file command line arguments:
$ native2ascii --reverse ascii.properties utf8.properties
# Using STDIN and STDOUT:
$ cat ascii.properties | native2ascii --reverse > utf8.properties

API

native2ascii(input[, options])

Converts the specified input so that it can be encoded in ASCII by using Unicode escapes ("\uxxxx" notation) for all characters that are not part of the ASCII character set.

This function is useful for properties files containing characters not in ISO-8859-1 character sets.

A reverse conversion can be performed by enabling the reverse option.

Options

Option	Description	Default
reverse	Whether to reverse the operation	false

Examples

Unicode escape characters not in the ASCII character set so that they can be safely written encoded into ASCII:

const native2ascii = require('node-native2ascii');

native2ascii('I ♥ native2ascii!');
//=> "I \u2665 native2ascii!"

These can be later unescaped by reversing the operation:

const native2ascii = require('node-native2ascii');

native2ascii('I \u2665 native2ascii!', { reverse: true });
//=> "I ♥ native2ascii!"
