Created attachment 160198 [details] LibreOffice doc. showing inter-pahe hyphens If Hyphenation is set to "Automatically" (in Paragraph Style > Text Flow), there is a problem with words hyphenating from one page to another. According to New Harts Rules (OUP, 2005, "Line Endings", p. 40), a recto (right-hand) page should not end with a hyphen (probably the same rule in the Chicago Manual of Style). This rule obviously applies to hard copy in book format; but for PC documents it also makes sense to apply the restriction on hyphenation to "verso" (left-hand) pages. For example, open the attached document. Look at the hyphenation from pp. 1-2, and 5-6. This is awkward to read. In a long document, you have to turn off hyphenation for each hyphenated "inter-page" word : this is time-consuming, and a document update may require you to do the whole thing over again. SUGGESTION: Add two tick-box options to the Paragraph Style > Text Flow TAB: 1. Don't hyphenate words from recto to verso pages. 2. Don't hyphenate words across any pages. Instead of hypenation, the last word will be moved, automatically, to the next page.
Reproduced the inter-page hyphenation with attached example in 6.4.4 RC1 on Windows. The enchancement request sounds very reasonable, setting to NEW.
It seems, this is also an interoperability problem, too: https://docs.microsoft.com/en-us/openspecs/office_standards/ms-docx/e0c0663e-a5e7-4a44-8360-b0b5df1f43e6
