--- Comment #4 from Fujii Hironori <Hironori.Fujii at sony.com> ---
This bug is caused by the following reasons:

1. Windows FontCache::systemFallbackForCharacters returns "Arial Unicode MS" font for some Tibetan characters, but it should be "Microsoft Himalaya".
   Bug 212688 – [Win] Some Tibetan characters aren't shown
2. ComplexTextControllerUniscribe simply ignores the complex text run if ScriptShape fails with USP_E_SCRIPT_NOT_IN_FONT
   Bug 212947 – [Win] ComplexTextControllerUniscribe: Retry ScriptShape with SCRIPT_UNDEFINED if it failed as USP_E_SCRIPT_NOT_IN_FONT
3. ComplexTextController::indexOfCurrentRun assumes the complex text runs are consecutive
   Bug 212944 – ComplexTextController: Use std::sort to calculate m_runIndices

Fixed in r262804 and r262803.
