Module Cf_unicode

module Cf_unicode: sig .. end

Unicode transcodings.

This module contains a collection of utilities for transcoding streams of Unicode characters between various encoding formats, i.e. UTF8, UTF16 and UCS4.

module type Encoding_T = sig .. end

The module type defining the relationship between UCS4 and a given UTF encoding of Unicode characters.

module E_utf8: Encoding_T

The UTF8 encoding

module E_utf16be: Encoding_T

The UTF16 encoding (big-endian)

module E_utf16le: Encoding_T

The UTF16 encoding (little-endian)

val any_utf_to_ucs4 : (char Cf_seq.t option, int) Cf_flow.t

A flow that transcodes any Unicode encoded character stream into a stream of 31-bit UCS4 integer codes. Determines the encoding format by reading the barker code from the beginning of the input stream.

val ucs4_to_utf16 : [< `BE | `LE ] -> (int, char) Cf_flow.t

Use ucs4_to_utf16 endian to compose a flow that reads a stream of 31-bit UCS4 integer codes and writes a stream comprised of the barker code followed by a stream of UTF16 characters in the 'endian' mode specified.

module type Transcoding_T = sig .. end

The module type that results from the application of the

C_create(E:
    Encoding_T)

functor below.

module C_create: functor (E : Encoding_T) -> Transcoding_T  with module E = E

The functor used to compose the transcoding modules defined below.
