[mrustl]

@hsonne any idea how I can resolve this?

Am besten nie und nimmer Umlaute verwenden!

Ja klar aber selbst das "µ" macht Probleme (hab ja alles in Unicode codiert....

z.B. https://github.com/KWB-R/kwb.pilot/blob/suleman/R/calculate_operational_parameters_berlin_f.R#L99

Can you try to replace \u00B5 with \xB5 and accordingly?

Unfortunately this suggestion is of the category: "I do not know what I do but I hope that it does what I want it to do".

Your proposed fix also didnt work :-(.
But I found out that it might be an issue within encoding in Windows compared to Linux

See: r-lib/roxygen2#1121 someone having problems with the greek mu in Windows but not under Linux and he wrote a work-around....
