JabRef 3.8.1 on Linux Mint 17.3

The Latex backslash tilde escaped diacritic "\~" does not display correctly in the entry table. So, for example, the bibtex entry of "Monta\~{n}a" displays as "Monta na". Note the space in the middle of the word. The "\" escape character seems to be ignored and the "~" character treated as a non-breaking space.
