As I'm unsure what is correct practice in the German language, the following question: Are half spaces (
\,
) mandatory in abbreviations consisting of multiple letters (e.g.
d.h.
or
d.\,h.
)? Normally I'd say the latter is correct, but found a
source (PDF) which states "Abbreviations always without spaces" (translated, orig. "Abkürzungen bitte immer ohne Leerzeichen schreiben")
