DIUnicode provides Unicode text reader and writer classes with automatic conversion from and to 144 character sets and encodings for Delphi (Embarcadero, CodeGear, Borland).

DIUnicode 6.10.0 – 7 Mar 2019

  • Fix potential TDIUnicodeWriter memory leak if TDIUnicodeWriteMethods.Init allocates its own memory.
  • TDIUnicodeWriter.Clear calls TDIUnicodeWriteMethods.Flush to reset encoder state.
  • KOI8-U converter now maps 0xB4 to U+0404 instead of U+0403.
  • Update DIUtils Unicode functions to Unicode 12.
  • Compatibility update with DIConverters 1.18.0. These changes only affect projects using DIConverters:
    • Add ISO-2022-CP-MS encoding: Read_iso_2022_jp_ms read methods and Write_iso_2022_jp_ms write methods.
    • DIConverters converter functions now use the native unsigned integer type for the length of a string and support stings longer than 2 GB.
    • UTF-8 converter functions reject surrogates and out-of-range code points, namely the in the ranges 0xD800..0xDFFF and >= 0x110000.
    • Fix error handling in UCS-2, UCS-4, and UTF-32 decoder functions.
    • Tweak the GB18030 converter functions to map 0x8135F437 to U+E7C7.
    • Update the CP1255 converter functions to map 0xCA to U+05BA.

  • Support Delphi XE3 Win32 and Win64.

DIUnicode 5.2.0 – 14 Apr 2012

  • Fix: When reading from TDIUnicodeReader.SourceStream, the size of the internal source buffer was not correctly calculated. Depending on the decoding, this slowed down reading or even stoped it before the end of the stream was reached.
  • Fix: TDIUnicodeReader.SkipEmptyLines consumed additional chars after the line break.
  • Work around a compiler warning in TDIUnicodeReader.FillSourceBuffer (source code edition only).
  • Add unit scope to demo projects.

DIUnicode 5.1.0 – 9 Nov 2011

  • Support Delphi XE2 Win64.

DIUnicode 5.0.0 – 15 Oct 2011

  • Support Delphi XE2 Win32 (binary editions) and Win64 (source code edition only right now).

DIUnicode 4.2.1 – 20 Feb 2011

  • Library source code compiles with FreePascal (Win32).

DIUnicode 4.2.0 – 28 Sep 2010

  • Delphi XE support.
  • New TDIUnicodeWriter.WriteStr8 and WriteBuf8 methods.
  • New TDIUnicodeReader.DataAsStrTrim8 method.
  • Improved help layout for better navigation and readability. Send your comments!

DIUnicode 4.1.1 – 17 Dec 2009

  • Additions and bug fixes to DIUtils.

DIUnicode 4.1.0 – 14 Sep 2009

  • Delphi 2010 support.
  • Update character properties, case folding, and case mapping to Unicode 5.10.

DIUnicode 4.0.1 – 31 Jan 2009

  • Work around an unexpected Delphi 2009 automatic numeric AnsiChar Unicode conversion in DIUtils.pas which caused a compiler error on Eastern European and Asian language settings.

DIUnicode 4.0.0 – 24 Nov 2008

  • Delphi 2009 support.

DIUnicode 3.2.1 – 30 Jul 2008

  • Improve compatibility for parallel installation with other DI packages.
  • Some code cleanup.

DIUnicode 3.2 – 13 May 2007

  • Delphi 2007 Support.
  • Compatibility with DIContainers 1.11.
  • Add XP Themes to Demo projects.

DIUnicode 3.1 – 28 Dec 2005

  • Added compatibility with Delphi 2006 Win32.

DIUnicode 3.0.1 – 14 Oct 2005

  • Fixed an error which could prematurely stop TDIUnicodeReader when a pushed source was popped at the end of a nested document.
  • Added Delphi 3 compatibility to the utility units.
  • Included the missing DIUnicodeCodePages.pas unit which is required to compile the FontCharSet example project.
  • Resolved dependency issues when DIUnicode is used in parallel with other DI products.

DIUnicode 3.0 – 14 Apr 2005

  • Added support for Delphi 2005 Win32.
  • Added TDIUnicodeReader.ReadBOM function which returns the Byte Order Mark (BOM) found at the current position and advances the position accordingly.
  • Added TDIUnicodeReader.SourceFile property as a simple means to read from a file.
  • Added optional WriteByteOrderMark parameter to TDIUnicodeReader.SaveDataToFile and TDIUnicodeReader.SaveDataToStream which controls if a UTF-16/UCS-2 little endian byte order mark is being written in front of the data.
  • Other, smaller improvements and bug fixes.

DIUnicode 2.00 – 2. February 2004

  • Added the possibility to link DIUnicode against DIConverters, which gives access to 130+ character encodings.
  • Added Pascal implementation for reading / decoding and writing / encoding the following character sets:
    • Mac Arabic, Mac Dingbats, Mac Central Europe, Mac Croatian, Mac Cyrillic, Mac Farsi, Mac Greek, Mac Hebrew, Mac Iceland, Mac Roman, Mac Romanian, Mac Thai, Mac Turkish
    • UCS-2 LE, CS-2 BE
    • UCS-4 LE, UCS-4 BE
    • UTF-32 LE, UTF-32 BE
    • UTF-7 (Write_UTF_7 / Read_UTF_7)
    • UTF-7 Optional Direct Characters (Write_UTF_7_ODC / reads as Read_UTF_7)
    • JIS X0201, NextStep, TIS 620
  • Bug fixes.

DIUnicode 1.50 – 13. December 2003

  • Added support for reading and writing UTF-7 according to RFC 2152. Writing UTF-7 comes in two flavors, with (Write_UTF_7) or without (Write_UTF_7_ODC) encoding optional direct characters. UTF-7 reading (Read_UTF_7) works equaly well for both writing methods.
  • Implementation of UTF-7 made it necessary to change the reading and writing implementation of TDIUnicodeReader and TDIUnicodeWriter to allow data buffering between consecutive reads and writes.
  • TDIUnicodeReader.PushSource and TDIUnicodeReader.PopSource methods added to which allow to insert one source into another, like for Pascal {$INCLUDE …} directive.
  • TDIUnicodeReader can optionally free its source stream if the reading reached the end of the stream. This is especially usefull when reading nested files using the TDIUnicodeReader.PushSource and TDIUnicodeReader.PopSource methods. The protected property TDIUnicodeReader.AutoFreeSourceStreams may be used by descendent classes which implement specialized reading / parsing.
  • Added Methods for reading digits and hexadecimal characters to TDIUnicodeReader, as well as for retrieving data as trimmed strings.
  • Various other improvements, code clean-ups and minor bug fixes.

DIUnicode 1.00 – 5. May 2003

  • Initial release.
