and to be compatible with non-etex
as I see an \ifx\undefined test is used also before, so let's do same

pdflatex  -file-line-error   
"\nonstopmode\nofiles\PassOptionsToPackage{active,tightpage,auctex}{preview}\AtBeginDocument{\ifx\ifPreview\undefined\RequirePackage[displaymath,floats,graphics,textmath,sections,footnotes]{preview}[2004/11/05]\fi}"
 
"{\ifx\UseRawInputEncoding\undefined\else\UseRawInputEncoding\fi\edef\x{\noexpand\input{primárias.tex}}\expandafter}\x"


If filename is containing # or ~ it must have them like \string# and \string~ 
in the above

(I made a brief test with file primárias~.tex and the above with 
\input{primárias\string~.tex} worked on command line)
