[Tex/LaTex] BibTeX loses capitals when creating .bbl file

bibtexcapitalization

Titles of articles I'm about to cite contain upper case letters and when using BibTeX it converts them to lower case ones. This happens only in the title and only the first letter conserves its case. For example, when I cite an article about HF, the reader won't know if it is about Hafnium (Hf) or fluorine acid (HF).

I know that I can fix it manually in the .bbl file but I would like to avoid it, or fix it automatically.

This is not a bug; it's a feature. Depending on the bibliography style in use, BibTeX converts all characters in the title to lowercase, with the exception of the first character. If you want to override this, wrap the character(s) in curly braces, e.g.,

title = "Pascal, {C}, {Java}: were they all conceived in {ETH}?"
