When creating a formula in Libreoffice Writer which takes the form "p(x|y)", the pipe symbol "|" gets converted to the logical or symbol "v". When I replace "|" with "divides", I can see the "|" symbol correctly now in the formula. However, when I save the result, close and open the document again, the logical or symbol "v" is back.
Confirmed with current master/7.0.0 alpha1+ Version: 7.0.0.0.alpha1+ (x64) Build ID: ec8dc357e68e20fa00a7d37f8c3195f571fb1fa6 CPU threads: 4; OS: Windows 10.0 Build 18363; UI render: Skia/Vulkan; VCL: win; Locale: en-US (en_US); UI: en-US Calc: threaded Roundtrip ODF retains the sm 'divides' syntax and renders formula with a "|" symbol. but on roundtrip with OOXML, 'divides' gets mishandled as "|" and parses it as the "V" logical OR.
