Crash or incorrect PDF generated with Noto fonts

[Shinjo Park]

When exporting an ODT file with Noto CJK family fonts as PDF, LibreOffice writer crashes or generates incorrect glyphs in the generated PDF file. Specifically, when there is an Ideographic Description Character [1] inside the document, exporting the document as PDF will crash LibreOffice. CJK glyphs in general is broken when there are no offending characters. The potentially related upstream bug is fixed around 5.0 series [2], and the upstream version of LibreOffice 5.4.5 successfully exports the ODT file in question. I've attached the file for reference.

After this version had been uploaded, the example ODT file could be successfully exported as PDF. At least this bug could be closed, unless there is other example.
