System Requirements
Tai Heritage Pro can be displayed using either the OpenType or Graphite rendering technologies. One of these technologies must be supported by both the operating system and the application software.
Graphite
The Graphite rendering for Tai Heritage Pro version 2.600 has been tested on Linux (Ubuntu 16), Windows 8.1, and Windows 10. Previous versions of the font were tested on Windows 7 and older versions of Ubuntu, and it is assumed that version 2.600 will work in these environments as well.
Tai Heritage Pro 2.600 has been successfully tested with the following Graphite-based applications: Firefox, LibreOffice (including Writer, Calc, Impress, and Draw), Thunderbird, Paratext* 7.5, and XeTeX*.
OpenType
Tai Heritage Pro 2.600 works on Windows 10 in applications that use the Universal Shaping Engine. It has been successfully tested in the following OpenType based applications on this platform: Notepad*, Chrome*, Edge, Internet Explorer, Outlook 2016, MS Word* 2016, MS Excel 2016, MS Publisher 2016, Paint*, and InDesign CC 2017.
Tai Heritage Pro 2.600 does not work in any application that uses the Uniscribe shaping engine found on older versions of Windows. While the characters will display properly, the combining vowels and tones will not always be positioned correctly, and will sometimes collide with adjacent characters.
Notes:
*Some minor issues show up in the above applications marked with an asterisk.
- In Notepad, combining marks are sometimes clipped off at the top, especially tone over vowel marks.
-
In Chrome, Paratext, Word, and XeTeX, the Graphite and OpenType rules that are designed to correct collisions across word boundaries do not work. Fortunately such collisions are quite rare.
WOFF support
WOFF (Web Open Font Format) is a font ‘wrapping’ technology that compresses the font data, so is more efficient (and faster) than referring to hosted TrueType or OpenType fonts. Further information on using and testing are available here:
