Issue with special characters in R code chunks

[cbeleites]

It seems each special character "eats" one character at the beginning of a comment* in the same line

* more precisely: after the end of R statements in that line

ϱ <- 1# g / ml
ϱ <- 1 # g / ml
ϱ <- 1  # g / ml
äöüßÄÖÜπ <- 7 + 3# nonsense

knits to the following markdown:

ϱ <- 1 g / ml
ϱ <- 1# g / ml
ϱ <- 1 # g / ml
äöüßÄÖÜπ <- 7 + 3se

In multiline statements, only the last line is affected:

äöüßÄÖÜπ <- 7 + # comment 1
3 + ϱ + # nonsense
3 + ϱ # nonsense

becomes

äöüßÄÖÜπ <- 7 + # comment 1
3 + ϱ + # nonsense
3 + ϱ# nonsense

Confirmed and reported to r-lib/evaluate#49 Thanks!

I have submitted a fix to evaluate, and you may test it by

devtools::install_github('hadley/evaluate@bugfix/49-srcref')

if you want. Or just wait for the next CRAN release.

Version 0.6 of the evaluate package is on CRAN now.
