Why have I this result (white rectangles) when I copy/paste tables in my NotePad++ ?
Because your font (Notepad++ menu Settings > Style Configurator > Language: Global Styles > Style: Default Style > Font name) doesn’t include glyphs for those characters. You might be able to toggle Settings > Preferences > MISC > ☐ Use Direct Write and restart Notepad++, and it might help the OS grab glyphs from other fonts to use in Notepad++ when your active font doesn’t have a specific glyph.
