4. One of the Biggest Challenges: Dealing with Complex Scripts Encoding Encoding –Transition to Unicode Input (Keyboarding) Input (Keyboarding) –Complexity –Extensibility Type Design Type Design –Unicode based –Smart-font compiler technology Rendering Rendering –Diacritic placement, Contextual shaping, Ligatures, Reordering/splitting, Bi-directionality

5. Solutions in Dealing with Complex Scripts Encoding Encoding –TechKit, a utility to convert legacy encodings to Unicode –http://scripts.sil.org: SIL resource site with information, tutorials, utilities, etc. for making the transition to Unicode Input Input –Keyman (Windows); http://tavultesoft.com http://tavultesoft.com –KMFL (a Linux ‘Keyman’ still under development) –IMEs (Input Method Editors) Type Design Type Design –Graphite Compiler adds Graphite rendering tables to a TrueType font, giving it ‘smart-font’ capability Rendering Rendering –Graphite rendering engine: Can handle basic display of any complex script in use today. NOTE: These technologies can benefit not only ‘complex scripts’, but also orthographies with special diacritics or a few non-Roman characters. NOTE: These technologies can benefit not only ‘complex scripts’, but also orthographies with special diacritics or a few non-Roman characters.

6. What is a Smart Font? A font containing data describing how the glyphs are to displayed. A font containing data describing how the glyphs are to displayed. The smart font data is in the form of tables inside the font file itself. The smart font data is in the form of tables inside the font file itself. A rendering engine interprets the font tables to appropriately render the glyphs. A rendering engine interprets the font tables to appropriately render the glyphs. In contrast, a ‘dumb font’ has only a direct correspondence between the data characters and the displayed glyphs. In contrast, a ‘dumb font’ has only a direct correspondence between the data characters and the displayed glyphs.

7. What is Graphite? A package, developed by SIL International, that can be embedded into other applications, adding "smart font behavior" to that application. A package, developed by SIL International, that can be embedded into other applications, adding "smart font behavior" to that application. This package includes the following: This package includes the following: –A programming language (GDL) for specifying the font's behavior –A compiler for building the smart font –A rendering engine for displaying text using the smart font Note that it is open-source: http://graphite.sil.org/ http://sourceforge.net/projects/silgraphite Note that it is open-source: http://graphite.sil.org/ http://sourceforge.net/projects/silgraphite http://graphite.sil.org/ http://sourceforge.net/projects/silgraphite http://graphite.sil.org/ http://sourceforge.net/projects/silgraphite

8. What Makes Graphite Special? It differs from other complex script technologies: It differs from other complex script technologies: –Unlike OpenType, it does NOT assume that script-specific information is incorporated at the application or operating system level (as in Uniscribe). –It is extensible, and provides support for characters in Unicode’s Private Use Area ranges … unlike Uniscribe, which handles only script behaviors already part of the Unicode standard. –It is an open-source solution versus proprietary. –It can handle basic display of any complex script in use today. –The following slides demonstrate the types of rendering difficulties that Graphite was designed to handle:

19. Lessons learned We are participating in or have created several open source development efforts. We have learned that… –FLOSS (Free/Libre Open Source Software) Linux is very attractive to low income groups we work with. –Setup and maintenance of open source OS and software is too complex for most of our end users. –Open source development is complex. –Getting support for complex minority scripts into the “core” builds of open source software is hard. –Localization of software is complex and time consuming. –Despite the difficulties, the benefits are great and we are heading in this direction on a number of fronts.

20. What is Keyman? Keyman allows you to enter text in Windows®-based applications in other languages without changing your physical keyboard (or system keyboard). Keyman allows you to enter text in Windows®-based applications in other languages without changing your physical keyboard (or system keyboard). It does this by remapping the character keys according to the font for the language you wish to use.

The development tool called ‘Keyman Developer’ is sold separately, and uses a rule-based programming language. Note: There are some issues with very large character sets that are handled better with IMEs (Input Method Editors). However, the IMEs are more complicated and are not really user modifiable or extensible.

30. Partnering in Script Development Things SIL International could potentially offer: – –Support script development for languages currently unsupported – –Partner in the development of keyboarding solutions – –Continued development of the Graphite rendering technology – –Support incorporating these technologies into current open source or commercial tools, e.g., Open Offiice Things SIL International would benefit from: – –Resources necessary to actually develop the scripts (people, money, hardware/software) – –Community cooperation in the standardization of scripts – –Help getting open source software groups to incorporate these technologies into their core software efforts
