Does R's package support unicode rd file? -

my platform is:

win7 64 rtudio r3.1.3 devtools 1.8.0 rxygen2 4.1.1 

i trying make package of own. need describe function unicode. used roxygen2 generate rd file. code simple(i removed real function know how make package):

xxxx means comment made unicode.

#' eastchoice #' @param fn.kind wind xxxxxx #' @param estchoice.path wind #' @return data.frame #' @export #' @examples #' getindbyeastchoice("20150108.csv") getindbyeastchoice <- function(fn.kind){   d <- data.frame(a=c(1,2,3), b=c(4,5,6))   dt <- data.table::data.table(d) } 

when check(devtools) r code, failed. following error information given:

* checking pdf version of manual ... warning latex errors when creating pdf version. typically indicates rd problems. latex errors found: ! package inputenc error: unicode char \u8:��<87> not set use latex.  see inputenc package documentation explanation. type  h <return>  immediate help. 

at first thought roxygen2 not support unicode other ascii, read rd file generated roxygen2, ok. , use build&reload function(using devtools), suprise, passed.

and add more unicode comment in r file , checked(devtools) again. following:

#' eastchoice xxxxxx #' @param fn.kind wind xxxxx #' @param estchoice.path wind xxxxxxxx #' @return data.frame xxxxxxx #' @export #' @examples #' getindbyeastchoice("20150108.csv") getindbyeastchoice <- function(fn.kind){   d <- data.frame(a=c(1,2,3), b=c(4,5,6))   dt <- data.table::data.table(d) } 

it failed expected, other information given , seems more serious:

* checking whether package 'ftools.temp' can installed ... error installation failed. see 'd:/onedrive/program/r.package/ftools.temp.rcheck/00install.out' details. 

so checked log:

* installing *source* package 'ftools.temp' ... ** r ** preparing package lazy loading ** *** installing indices wrong in gsub("&", "&amp;", x, fixed = true) : '<86>'multi byte string wrong * removing 'd:/onedrive/program/r.package/ftools.temp.rcheck/ftools.temp' 

and time build&load failed.

so think maybe r not support unicode other ascii in rd file? can 1 confirm it? if true, not waste time trying solve problem.

@hrbrmstr thank you. have tried advice. first, added line "encoding:utf-8" in decription file, , saved .r , description coding utf-8 ensure encode correct. , run "check " function, got same error:

strsplit(txt, "\n", fixed = true)���о���: �������ַ���1����utf-8 * checking examples ... ok * checking pdf version of manual ... warning latex errors when creating pdf version. typically indicates rd problems. ����: ��������'"d:/r/r-31~1.3/bin/x64/rcmd.exe" rd2pdf  --batch --no-preview --build-dir="c:/users/kanpu/appdata/local/temp/rtmpgfjykw/rd2pdf15f2c22b7768d" --no-clean -o  ftools.temp-manual.pdf  "d:/onedrive/program/r.package/ftools.temp.rcheck/ftools.temp"'��״̬��1 latex errors found: ! package inputenc error: unicode char \u8:��<97> not set use latex. 

the description this:
