Created attachment 168448 [details] Screenshot Right click on a toolbar button, then choose "Visible Buttons". Notice how "Symbol" shows up twice.
On pc Debian x86-64 with LO Debian package 7.0.4, I could reproduce this. Heiko/Xisco: thought you might be interested in this one.
I used keyid and searched in French translation part. One corresponds to: 23182 #. oBjzB 23183 #: GenericCommands.xcu 23184 msgctxt "" 23185 "GenericCommands.xcu\n" 23186 "..GenericCommands.UserInterface.Commands..uno:InsertSymbol\n" 23187 "Label\n" 23188 "value.text" 23189 msgid "Symbol" 23190 msgstr "Symbole" the other: 23212 #. KXPE3 23213 #: GenericCommands.xcu 23214 msgctxt "" 23215 "GenericCommands.xcu\n" 23216 "..GenericCommands.UserInterface.Commands..uno:CharmapControl\n" 23217 "Label\n" 23218 "value.text" 23219 msgid "Symbol" 23220 msgstr "Symbole" both are in officecfg/registry/data/org/openoffice/Office/UI.po
The hidden "Symbol" button is what we had before 2017 [1], and what is accessed now per "More Characters..." from the floating widget. Perhaps it's time to remove this hidden button from the toolbar.
