(What tool do you use to de-compress/analyse PDFs?)

Here's the PDF file generated with Word 2010:

The bad text is this (only contains two diacritics but word has chewed
the whole paragraph):
1035800030057>4<017D>-5<016F0190019A>10<011E018C>] TJ

There's a CMAP included:
/CMapName /Adobe-Identity-UCS def
/CMapType 2 def
1 begincodespacerange
<0000> <FFFF>
17 beginbfchar
<0003> <0020>
<0011> <0020>
... repeated for all chars above mapping to 0020
<0358> <0020>
CMapName currentdict /CMap defineresource pop

Do I understand correctly that Word is encoding all paragraphs
containing diacritics using a custom font table with a Unicode cmap that
maps every character to space (which is exactly the behaviour shown by
Chrome copy-n-paste)?

All the best,
