modules/javafx.graphics/src/main/java/com/sun/javafx/font/freetype/PangoGlyphLayout.java line 148: > 147: long utflen = OSPango.g_utf8_strlen(str,-1); > 148: long end = OSPango.g_utf8_offset_to_pointer(str, utflen); > 149: long runs = OSPango.pango_itemize(context, str, (int)(start - > str), (int)(end - start), attrList, 0); Since you are now creating `n` native strings, 1 per substring based on the `TextRun`, rather than 1 for the entire String, isn't the `start` pointer wrong? Unless I am missing something, I would think that `start` should be set to `str`. ------------- PR: https://git.openjdk.java.net/jfx/pull/249
