Package: libreoffice-writer
Version: 1:5.2.7-1+deb9u3
How to reproduce:
1) Open a fresh writer document.
2) Type in "Ph.D." (without quotation marks).
3) Mark the text as "English (USA)".
Observe that the abbreviation is underlined with a wave in red as if it were an error. Removing the periods makes the warning go away. This misleads the reader into thinking PhD is generally preferred over Ph.D. in the US English, which is generally NOT the case.
Reasons:
- OED lists this as the main dictionary entry, cf. https://en.oxforddictionaries.com/definition/us/ph.d.
- On a personal experience, a personally known professional editor who is also a native English speaker corrected my PhD to Ph.D. in a text explicitly marked as a US English text.
Since I'm not aware of which package is responsible (libreoffice, aspell, hunspell, or ispell), I am submitting a bug against libreoffice-writer. Feel free to solve the problem yourself or redirect appropriately.
Thanks in advance,
Vasili
