To have author names be listed as e.g. Doe, J.D. in the references (i.e. no space between initials). I use in my .bbx file:
\ExecuteBibliographyOptions
{
firstinits = true,
terseinits = false
}
But the result is Doe, J. D. with spaces between the initials.
I tried adding \renewcommand\bibinitdelim{\nospace} to the .bbx file but that gives an error.
Question: any way to suppress the space between author's name initials (with or without calling
terseinits = false)?

\renewcommand*{\bibinitdelim}{\,}– egreg Nov 09 '12 at 14:34\renewcommand*{\bibinitdelim}{}works like a charm). – Roey Angel Nov 09 '12 at 14:46\,adds a non-breakable thin space. – lockstep Nov 09 '12 at 14:47
