Appendix A: Writing system tags

Features are encoded according to both a designated script and language system. Currently, the Uniscribe engine only supports the "default" language for each script. However, font developers may want to build language specific features which are supported in other applications and will be supported in future Microsoft OpenType implementations.

* NOTE: It is strongly recommended to include the "dflt" language tag in all OpenType fonts because it defines the basic script handling for a font. The "dflt" language system is used as the default if no other language specific features are defined or if the application does not support that particular language. If the "dflt" tag is not present for the script being used, the font may not work in some applications.

The following tables list the registered tag names for scripts and language systems.

Registered tags for the Kannada script Registered tags for Kannada language systems
Script tag Script Language system tag Language
"knda" Kannada "dflt" *default script handling
"KAN " Kannada

Note: both the script and language tags are case sensitive (script tags should be lowercase, language tags are all caps) and must contain four characters (ie. you must add a space to the three character language tags).


Appendix B: Consonant forms

In the table, consonants that have a reph form, below-base form and post-base form will have a check mark in those columns. All consonants are expected to have a half form, which can be a combination of the full form and a virama (halant).
