Hi there, It seems page break is lost when saving as UTF-8 file in both possible situations:- 1. Page break is already in existing file (open as encoding UTF-8) text file. 2. When inserting a page break from menu using Alt-I and selecting page break (or CTRL+ENTER). Before saving it shows page break properly as it should. However after saving the file (again as text but choosing encoding of UTF-8) or even via save as. It appears that page breaks are converted to CR LF pair of 0x0D and 0x0A when it is saved. It is reproducible at will. Just create a blank document, type test1, insert page break from the insert menu or using CTRL+Enter , type in next line test2 and enter another page break. After saving this file as text with encoding of UTF-8, and reopening will no longer have page breaks; instead it will display additional blank lines. It looks like this matches with BUG ID: 116573, 130238, 155722 though in my case it is not an RTF file but UTF-8 text file mixed with multilingual sentences from two three languages.
I can confirm the problem with Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 4871de96cb5e31e5ab06cf97e02e09e0e04a4de8 CPU threads: 32; OS: Windows 10.0 Build 22631; UI render: default; VCL: win Locale: de-DE (de_DE); UI: en-US Calc: threaded 0C (form feed) is read as page break but exported as 0D0A.
