Our Approach Our Approach (or: How did we get where we are today?)(or: How did we get where we are today?)
Include full Unicode support from onset Leverage Uniscribe, OpenType, NLS Migrate towards a single worldwide
source (reached in Windows 2000) Develop and refine Multilingual User
Interface functionality Continue to add new international
functionality (Windows Text Services Framework, etc.)

Our History Our History (or: Well, how did we get here?)(or: Well, how did we get here?)
Genesis of NT (1991): Go with Unicode! NT 4.0 (1996): many Unicode components,
but still strong code page dependency 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

National Language SupportNational Language Support
NLS provides the information that supports culturally appropriate behavior:
Sorting and casing Formatting (dates, times, currency,
numbers) Conversions (normalization, character
encodings) Other (calendars, native digits)

National Language Support, cont.National Language Support, cont.
NLS data for a particular culture grouped into a locale (generally, a country + language combination).
There were different types of “locales” on Windows 2000, which have been renamed for Windows XP (as seen in Regional Options)…

MUIMUI
Short for Multilingual User InterfaceMUI changes language of the
system’s menus, dialogs and Help files into one of 24 different languages
Available as add-on pack for Windows XP Professional (Multilingual User Interface Pack)

MUI, continuedMUI, continued
MUI built by copying resources from localized versions
Testers check for same issues as for localized versions
Resource loader checks user’s UI language setting to load the appropriate resources

MUI vs. other international MUI vs. other international functionalityfunctionality
MUI– changes the user’s UI language– only available as an add-on pack to the
English version of Windows XP
All other international functionality– impacts language content and
formatting– available on all versions of Windows XP

If you take away just one thing If you take away just one thing from this talk…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 MUI version Base (English) version

Well, what about us Win9x fans?Well, what about us Win9x fans?
Gee, not everyone can go out and buy Windows XP tomorrow…
Some of us have a customer base on Windows 95/98/ME…
We’d love to be able to write Unicode apps, but we have to run on both NT and Win9x…

Goals: extend the NT set of Unicode APIs to the
Windows 95/98/ME platforms provide a means for customers to
reasonably compile Unicode versions of their applications
further promote the use of Unicode

Why MSLU?Why MSLU?
Too much need for single binary on NT and Win9x platforms
Cannot fully leverage Unicode without some support mechanism on down-level Win9x platforms
MS needed to provide a solution that is included in the Platform SDK
