4. Unicode Guide Authoritative but lightweight Introduction, overview, and quick reference Main principles of the Unicode Standard Best practices in Software Globalization See Globalization Gotchas at this conference

5. Language Tags RFC3066 replacement approved: 2005-11-15 Not yet published, but registry now operating http://inter-locale.com/ID/draft-ietf-ltru-registry-14.html Addresses problems in RFC3066 Stability / accessibility / ambiguity of the underlying ISO standards Parseability, Extensibility; Registration speed Identification of script (where necessary): Traditional Chinese (zh-Hant), Serbian in Latin (sr-Latn), Azerbaijani (Cyrillic) az- Cyrl, etc.

6. Common Locale Data Repository: CLDR Common, necessary software locale data for world languages XML format for effective interchange Δευτέρα, 05 Σεπτεμβρίου 2005 Montag, 5. September 2005 1,234.57 1 234,57руб. Arabic – arabski Bulgarian – bułgarski Czech – czeski … Africa – Central America – Eastern Africa – Northern Africa – … AED – د.إ. BHD – د.ب. DZD – د.ج. EGP – ج.م. EUR – … Z < Å

7. CLDR 1.4 Features Repository separated into language vs locale data Language-specific segmentation (word/line breaks…) Transliterations (eg Ελληνικά Ellēniká) Data for lenient date/time formatting and parsing Programmer asks for numeric day + abbreviated month Best format pattern returned, eg dd.MMM Algorithm and locale data for choosing, adjusting Calendar usage data Quarters in dates (eg 2006Q1)

8. CLDR 1.4 Schedule Gathering data phase:currently Vetting phase start:March 15 Release:May 15 Aside from features: New data, corrections Metadata for parsing & validation New tool for gathering/vetting data

9. CLDR Survey Tool New web tool for data submission Unicode members and others Automatically incorporated into XML Process for resolving differences, approval by committee

10. CLDR Vetting Process Vetters confirm or approve new translations, corrections Errors and alerts for areas of concern Data accepted when approved by multiple organizations (plus exception process).

11. Unicode Security Issues Examples: Visual Confusables: paypal.com with Cyrillic a… Non visual problems: buffer overflows, non-shortest form,… UAX #36: Unicode Security Considerations Process recommendations Best practices UTS #39: Unicode Security Mechanisms Limitations on Repertoire Testing for Confusables See Unicode Security at this conference

12. Internationalized Domain Names Unicode Recommendations Narrow the repertoire: exclude symbols, punctuation Expand the coverage: currently only Unicode 3.2. Broader problem; many RFCs use Nameprep, but that is limited to Unicode 3.2 New ICANN Guidelines (2.0) Improved, but needs more work. IETF idn-nextsteps Positive developments, but misreads Unicode, needs more work
