Description Gabor Kelemen 2017-10-27 13:17:15 UTC
Created attachment 137322 [details]
Sample file

Attached file contains a bookmark named "Első" and a cross reference to it.

After saving to DOCX format and reloading the cross reference becomes "Els%C5%91" while the bookmark still says "Első" and the reference breaks.

After hitting space in the paragraph with the broken reference the referenced text is replaced with "Error: Reference source not found" in the document.

I can't reproduce it in

Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build

Example file saved as docx then resaved again

In 6.0 alpha it is not broken the same way. 
Now the bookmark name changes as well: while it becomes an unreadable "Els%C5%91" it is consistent with the reference name, so they work.
After one more resave to docx the names become: "Els%25C5%2591" - even harder to read, but still consistent.

Comment 6 Dieter 2017-10-28 09:25:18 UTC
I could reproduce it:

1. Open attachment from comment 3
3. Save as docx
4. Open "fields" in the context menu of the cross-reference => Name of the bookmark is Első
5. Save as docx
6. Close and reopen
7. Open "fields" in the context menu of the cross-reference => Name of the bookmark is Els%C5%91

I couldn' reproduce the folloing behaviour: "After hitting space in the paragraph with the broken reference the referenced text is replaced with "Error: Reference source not found" in the document."

Comment 9 Adam Kovacs 2019-03-18 11:10:35 UTC
How to reproduce (the example document with the bug) in Writer (6.3):
1. create some text (for example write "lorem" and hit f3)
2. select some section of the text (for example the first sentence)
3. click on insert menu, select bookmark
4. give it a name which contains non-ASCII characters (for example Első)
5. go to somewhere else in the document, for example to the end in a new line
6. click on insert menu, select cross-reference
7. select the value "Bookmark" in "Type" listbox, then select the value "Reference" in the "Insert reference to..." listbox
8. in the "Selection" listbox, double click on the previously named bookmark
9. save the file as docx and reload it

The bug is because the bookmark name will be converted to Els%25C5%2591, but the cross-reference still point at Első

Comment fix: until the version
Comment 12 Adam Kovacs 2019-03-18 12:35:04 UTC
So the reference is not broken in the version, but of course, the non ASCII characters will be converted. For example ő to %C5%91.
Comment 13 Adam Kovacs 2019-05-02 09:26:08 UTC
bookmarkName and sToken need to be decoded

sToken = INetURLObject::decode(sToken, INetURLObject::DecodeMechanism::Unambiguous, RTL_TEXTENCODING_UTF8);
Comment 14 Adam Kovacs 2019-05-02 10:42:10 UTC
In document.xml, the these are the related xml tags:
<w:bookmarkStart w:name="Els%C5%91" w:id="0"/>
<w:instrText> REF Els%C5%91 \h </w:instrText>

Comment 16 Timur 2019-05-16 13:26:29 UTC
Verified for DOCX. Backport to 6.2 wouldn't hurt, I guess. 
DOC is still wrong. 
Adam, could you handle DOC here or we should open a new one?
Comment 17 László Németh 2019-05-28 06:19:08 UTC
Timur: it's better a new bug report for the obsolete DOC, if it's really needed. We'll check the back-port, too. Thanks for the verification!
