This page relates to Bug 0001547: - Support for Indic Scripts and Metabug 0003965: Support for non-latin languages].
Things we require for testing Complex Script Functionality
- Sample text files encoded in UTF8
- Sample screenshots of Scribus 1.4.1 or 1.5.0svn rendering these incorrectly.
- Sample fonts that we can get that are freely available that have the ability to be used for DTP.
- Sample screenshots of any application rendering the same text correctly
- An important point to note is we need comparable information. Same texts, same fonts etc and screenshots (png or tiff please) of said texts and fonts. --Cbradney 18:40, 25 Feb 2005 (UTC)
- It would also be helpful to add information about the writing direction(s).--C schaefer (talk) 06:52, 22 December 2012 (CET)
- Other useful contribution would be mapping of the languages you're interested in with its script/lang pair in OpenType Font style.
example : French:latn:FRA
To help, you can have a look at http://www.microsoft.com/typography/developers/OpenType/scripttags.aspx for script tags and http://www.microsoft.com/typography/developers/OpenType/languagetags.aspx for lang tags. --Pmarchand 13:46, 8 April 2007 (CEST)

Tibetan & Dzongkha
This relates to Bug 0004452: No support for Tibetan Script - sample UTF-8 test file and PDF file attached to that bug.
Tibetan Script:
- Unicode Range: 0F00 - 0FFF Tibetan Unicode Range
- Typing order: Left ==> Right
- OpenType Specs: Creating and Supporting OpenType Fonts for Tibetan Script
Fonts:
- Jomolhari, a free Tibetan script font suitable for publishing is available from the Free Tibetan Fonts project - OFL License. The font was originally designed for publishing traditional Buddhist texts in Classical Tibetan (chos skad) - but can also be used for modern Tibetan, Dzongkha and Ladakhi text. The font works well in OO.org 2.4.x & Inkscape.
- DDC Uchen OFL License. Freely available from the Dzongkha Development Commission
Language Script & Language System tags:
- Tibetan: tibt:dflt (default)
- Tibetan: tibt:TIB
- Dzongkha: tibt:DZN
- Sanskrit: tibt:SAN
- Ladakhi: tibt:LDK
- Tshangla: tibt:TSJ
- Khengkha: tibt:XKF
- Bumthangkha: tibt:KJZ
- Balti: tibt:BFT
OpenType Features
The following OpenType features should be processed to support Tibetan script:
- ccmp - Glyph Composition / Decomposition (Composition = GSUB lookup type 4 & Decomposition = GSUB lookup type 2).
- blws - Below-base Substitutions (GSUB lookup type 4)
- abvs - Above-base Substitutions (GSUB lookup type 4)
- calt - Contextual Alternates (GSUB lookup type 6)
- blwm - Below-base Mark Positioning (GPOS lookup type 4,5)
- abvm - Above-base Mark Positioning (GPOS lookup type 4,5)
- kern - Kerning - (GPOS lookup type 2 or 8)
Note: The current version of the Jomolhari font uses only ccmp, blws, abvs, calt, and kern features. In kern only GPOS lookup type 2 (pair-adjustment) is used in this font ~ so this is the only kind of GPOS lookup used.
Tibetan Script Rendering Examples:
Test of ccmp feature used for Decomposition (GSUB lookup type 2):
The string U+0F43 U+0F77 (གྷཷ) should render like the first example:
In this case, the ccmp feature should decompose U+0F77 into seperate glyph components to go below and above the glyph for the base character (U+0F43)
Test of ccmp feature used for Composition (GSUB lookup type 4):
The string U+0F42 U+0FB7 U+0F0B U+0F4C U+0FB7 U+0F0B U+0F51 U+0FB7 U+0F0B U+0F56 U+0FB7 U+0F0B U+0F5B U+0FB7 U+0F0B U+0F40 U+0FB5 (གྷ་ཌྷ་དྷ་བྷ་ཛྷ་ཀྵ) should render as follows:
In this case if ccmp feature is being applied ligatures should be properly composed.
Furthermore, the strings U+0F42 U+0FB7 U+0F0B U+0F4C U+0FB7 U+0F0B U+0F51 U+0FB7 U+0F0B U+0F56 U+0FB7 U+0F0B U+0F5B U+0FB7 U+0F0B U+0F40 U+0FB5 (གྷ་ཌྷ་དྷ་བྷ་ཛྷ་ཀྵ) and U+0F43 U+0F0B U+0F4D U+0F0B U+0F52 U+0F0B U+0F57 U+0F0B U+0F5C U+0F0B U+0F69 (གྷ་ཌྷ་དྷ་བྷ་ཛྷ་ཀྵ) should render identically as they are canonically equivalent. (U+0F42 U+0FB7 = U+0F43; U+0F4C U+0FB7 = U+0F4D; U+0F51 U+0FB7 = U+0F52; U+0F5B U+0FB7 = U+0F5C; and U+0F40 U+0FB5 = U+0F69.)
Test of blws feature (GSUB lookup type 4)
Test string consists of the folowing Unicode characters:
U+0F62 U+0F0B U+0F62 U+0F90 U+0F0B U+0F62 U+0F90 U+0FB1 U+0F0B U+0F62 U+0F90 U+0FB1 U+0F74 U+0F62 U+0F92 U+0F0B U+0F62 U+0F92 U+0FB1 U+0F0B U+0F62 U+0F92 U+0FB1 U+0F74 U+0F0D (ར་རྐ་རྐྱ་རྐྱུརྒ་རྒྱ་རྒྱུ།) and
Test of abvs feature (GSUB lookup type 4)
