Description

« Hide

Current SL viewer renders texts by a combination of home brew UI components (i.e., LLTextEditor, LLLineEditor, LLTextBox, etc.) and FreeType font renderer. The current mechanim is insufficient to cover more languages/writing systems. In particular, the current viewer can't handle Unicode conbining characters, ligatures, no space-based line breaking, right-to-left scripts, etc.

Pango is an open source library that handles all of such world-wide text processing headaches. Use of pango in SL viewer will significantly enlarge the language/writing system coverage.

(See http://wiki.secondlife.com/wiki/User:Alissa_Sabre/Pango_adaptation_in_SL_viewer for details.)
