Consider the soon-to-be attached documents. It is a formal letter, in the Hebrew language - one of the most popular kinds of documents people use Word Processors for.

We start with the letter in LO Writer (I've replaced the actual text with gibberish, mostly). Actually, there's a bit of a fib here, since this document might have, at some point in the past, been an opened DOCX that got modified, so not written from _scratch_ in Writer probably. But, be that as it may - we now:

1. Save letter as ODT; this is the first attachment
2. Open the letter with MS Office Word 16, on Windows.
3. Save the letter as a Word Document, i.e. DOCX, in MSO Word; that DOCX is the second attachment.
4. Open the DOCX file in LibreOffice

Comparing the two documents in LO Writer, we observe several differences:

1. Some paragraphs - but not all of them - have LTR rather than RTL direction.
2. The originally left-aligned first paragraph, when flipping its direction to RTL - doesn't become left-aligned again, but right-aligned; and then if we flip again, it _does_ become left-aligned, i.e. doesn't revert to LTR and right-aligned
3. The title paragraph is no longer centered
4. The underline width for the "Title Subject Part" text is thinner than it was originally.
5. The DF paragraph border for the Default Paragraph Style second-to-last paragraph (which is actually not very well formatted, it should have its own style, but that's not a bug, just a gaffe on my part with the original document) - loses its bottom border in the DOCX.
6. The "Body Text" paragraphs now have style "Text Body (WW)"
7. The "Body Text" paragraphs are now no longer justified, but right-aligned
8. The first two characters in the first paragraph are rendered as "English, USA", i.e. with the Western LG font - even though Writer _is_ able to figure out the rest of the paragraph, including the trailing numbers, are "Hebrew"


Now, some of these issues are likely already-reported bugs. For those, let's mark this bug as blocked by those issues. For yet-unreported bugs, let's add the report and then mark the new bugs as blocking this one.
