Hi, ZnCharacterEncoder and its subclasses in the package Zinc-Character-Encoding-Core (a standard part of Pharo) have the following features: - proper Unicode Character/String to/from byte(s) encoding/decoding - calculation of encoding size per Character/String - proper handling of holes in tables with exceptions (strict/lenient) - properly backing up one character on a binary stream - simple, efficient, documented - convenience API - optimisations for some encodings Together, they support the following encodings: - utf-8 - utf-16 (big/little endian, bom detection) - null - iso-8859-1 (latin-1) - iso-8859-2 (latin-2) - mac-roman - cp1250 - cp1252 - cp1253 - koi8r - iso-8859-7 - iso-8859-15 The question is, what other encodings do you want/need ? There is already a request to add CP1251. New byte encoders are easy to add, based on the official Unicode mappings that can be found here: http://unicode.org/Public/MAPPINGS (these are automagically parsed). Please help us make Pharo more international friendly. Sven
