I have studied that problem on Internet and I still cannot the solution to the following warning. In .log file I get 20 times

Missing character: There is no p in font nullfont!
Missing character: There is no t in font nullfont!

and I obviously don't use "pt" anywhere. Is it possible that there is a problem in arrows.meta? MWE:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}

\begin{document}

\begin{tikzpicture}
\draw[line width=7,-{Triangle[angle=60:1 1.5]},postaction={draw,white,line width=6,shorten <=0.5,shorten >=0.9}] (6.36,9.5) -- (5.1,9.5);
\end{tikzpicture}

\end{document}

    @Johannes_B Have you checked .log file?

    This is the result of unnecessary pt in the PGF code. Something like \somedimen=#1pt where #1 was expected to be a number without units but had units so the pt is output into the document. However inside a tikzpicture the font is set to \nullfont resulting in these warnings. Dec 15 '14 at 9:34

    @Pygmalion This has been reported multiple times. See also tikzpicture options causing "There is no [ in font nullfont!"? The code behind pgf is HUGE and it is just a warning.

    Some tickets for this bug (1, 2) already exist. Dec 15 '14 at 10:57

    This question appears to be off-topic because it is about a but which has been reported (links included in comments). But the question ought not be deleted as it is likely others encounter the same bug. (It may also be a duplicate here - I'm not entirely clear about that.)
