3. Approach and History

4. 12 September 2002 4 Unicode and Windows XP, IUC 22 (San Jose) Just what is “Windows” anyhow? Windows XP Windows 2000Windows ME Windows NT 4 Windows 95 Windows 98 Win NT 3.5, 3.1 “Win NT”“Win 9x”

5. 12 September 2002 5 Unicode and Windows XP, IUC 22 (San Jose) Our Approach Include full Unicode support from onset Include full Unicode support from onset Leverage Uniscribe, OpenType, NLS Leverage Uniscribe, OpenType, NLS Migrate towards a single worldwide source (reached in Windows 2000) Migrate towards a single worldwide source (reached in Windows 2000) Develop and refine Multilingual User Interface functionality Develop and refine Multilingual User Interface functionality Continue to add new international functionality (Windows Text Services Framework, etc.) Continue to add new international functionality (Windows Text Services Framework, etc.)

6. 12 September 2002 6 Unicode and Windows XP, IUC 22 (San Jose) Our History (or: Well, how did we get here?) Genesis of NT (1991): Go with Unicode! Genesis of NT (1991): Go with Unicode! NT 4.0 (1996): many Unicode components, but still strong code page dependency NT 4.0 (1996): many Unicode components, but still strong code page dependency NT 5.0, renamed Windows 2000 (2000): single worldwide source NT 5.0, renamed Windows 2000 (2000): single worldwide source Windows XP (2001): merge of the NT international functionality with the consumer experience of Windows 95/98/ME Windows XP (2001): merge of the NT international functionality with the consumer experience of Windows 95/98/ME

24. 12 September 2002 24 Unicode and Windows XP, IUC 22 (San Jose) If you take away just one thing from this talk… As a result of pervasive Unicode support built into Windows XP, international functionality (except MUI) is available on all versions This includes: Localized versions Localized versions MUI version MUI version Base (English) version Base (English) version

25. What’s coming?
