You forgot the 'at a minimum' information required by the posting
guide.
Most likely this is a limitation of the locale you used (and failed to
tell us about) on the OS you used (...).

Dear helpers,
I'm trying to replace a character with a unicode code inside a data
frame using gsub(), but unsuccessfully.
data.frame(animals=c("dog","wolf","cat"))->my.data
gsub("o","\u0254",my.data$animals)->my.data$animals
my.data$animals
[1] "dɔg" "wɔlf" "cat"
It's not that a data frame cannot have unicode codes, cf. e.g.
data.frame(animals=c("d\u0254g","w\u0254lf","cat"))->my.data.2
my.data.2$animals
[1] dɔg wɔlf cat
Levels: cat d<U+0254>g w<U+0254>lf
I've done the best I can based on what ?gsub and ?enc2utf8 tell me,
but I haven't found a solution.
Unrelated to that problem, but related to gsub() is that I can't find
a way for gsub() to interpret the backslash as a character. In regular
expression, \\ should represent "the character \", but gsub() doesn't:
data.frame(animals=c("dog","wolf","cat"))->my.data
gsub("d","\\",my.data$animals)
[1] "og" "wolf" "cat"
Thank you
Sverre
