jEdit 5.4.0 on Debian Linux "stretch".
When pasting in LibreOffice Writer 5.2.7.2 for Debian Linux (GTK3), Locale: en-US (en_US.UTF-8) a text copied from jEdit is damaged:
Bravo::Kassy::PrintDispatcher
-> ... #B#r#a#v#o#:#:#K#a#s#s#y#:#:#P#r#i#n#t#D#i#s#p#a#t#c#h#e#r
Note that the file in jEdit from which I copied, was in UTF-8 mode.
Cannot reproduce with Libreoffice Writer 5.1.6.2 on Kubuntu Linux with KDE.
Can not reproduce. jEdit text mode, Writer 5.4.2.2 (x64), Win7.
Can't reproduce on macOS 10.12, LibreOffice 5.4.1.2
Can't reproduce on Linux jEdit 5.4.0, LibreOffice 5.4.2.2.0.
Works for me also, closing.
