How to remove non UTF-8 characters from text

Question

I need help removing non UTF-8 character from my word cloud. So far this is my code. I\'ve tried gsub and removeWords and they are still there in my word cloud and I do not know

Answer 1

The signature of gsub is:

gsub(pattern, replacement, x, ignore.case = FALSE, perl = FALSE, fixed = FALSE, useBytes = FALSE)

Not sure what you wanted to do with

gsub("’","‘","",txt)

but that line is probably not doing what you want it to do...

See here for a previous SO question on gsub and non-ascii symbols.

Edit:

Suggested solution using iconv:

Removing all non-ASCII characters:

txt <- "’xxx‘"

iconv(txt, "latin1", "ASCII", sub="")

Returns:

[1] "xxx"
