Comment 4 László Németh 2024-06-18 11:37:07 UTC
It seems, MSO doesn't follow the OOXML standard, using unknown hyphenation zones depending on the language of the operating system. For example, the attached document got 425 twips from Office 365 instead of the standardized 360 on a Hungarian operating system.

Microsoft "Open specification" mentions the difference, but the values are not open: https://learn.microsoft.com/en-us/openspecs/office_standards/ms-oe376/660d0f16-dffb-48ea-a25d-7210fb2f2a7a
