No separating spaces in source code generated by knitr in case of Unicode variable characters (Greek)
I tried to inject variables into R code using LaTeX text and knitr.
The problem is with the formatting of the source code. In the case of Greek, there are no delimiting spaces.
You see?
Rnw source:
\documentclass{article}
\usepackage[T2A]{fontenc}
\usepackage[utf8x]{inputenc}
\usepackage{textgreek}
\begin{document}
<<>>=
Ξ± <- 1
Ξ² <- 2
Ξ³ <- Ξ± + Ξ²
Ξ±
Ξ²
Ξ³
a <- 1
b <- 2
c <- 3
d <- a + b + c
a
@
\end{document}
And this is tex: 
How can I fix this?

Before it's committed to the R base, your only choice is to turn off syntax highlighting (or avoid multibyte characters in object names):
<<highlight=FALSE>>=
