npm

Provides an interface for encoding and decoding among character sets.

var Transcoder = require("transcode").Transcoder;
var Buffer = require("buffer").Buffer;
var transcoder = new Transcoder(sourceCharset, targetCharset)
var state = {
    "source": new Buffer(10),
    "target": new Buffer(10)
};
transcoder.transcode(state);

The state object can be initialized with and may be updated to include:

• source: the source buffer
• target: the target buffer
• sourceStart: the read head, defaults to 0
• sourceStop: the read boundary, defaults to start.length
• targetStart: the write head, defaults to 0
• targetStop: the write boundary, defaults to target.length
• error: an error message, if one occurs, one of:
  • "resize"
  • "invalid"
  • "incomplete"
• message: human readable form of the error
• nonReversible: an accumulator for non-reversible character conversions
