I am trying to remove characters from specific words from twitter text mining, lamentably my text has wrong word and ending because of accent:

my result: â€œuna muriÃ

result expected: una murio

I am using gsub :

mach_text = gsub("una$,"", ignore.case=T, mach_text)

Pd: I am working with Spanish text and lamentably my text have word ending because accent, I did try with:

mach_text = iconv(mach_text, "latin1")

But doesn´t work. Thanks in advance

Do you want `una muri`?? – Onyambu Mar 04 '18 at 20:22
I don't code in R but it looks like you have some typos. – eesiraed Mar 04 '18 at 20:26
@Onyambu I want: "una" and "murio" – Rodrigo B Mar 04 '18 at 20:28
In your code I mean. – eesiraed Mar 04 '18 at 20:28
what is the `Encoding(mach_text)`? – Onyambu Mar 04 '18 at 20:29
How will it change the last character in `muriA` to `O`? Which encoding? – Onyambu Mar 04 '18 at 20:31
@Onyambu I did try using mach_text = gsub("muri", "murio", ignore.case=T, mach_text ) Works fine but not for "una". – Rodrigo B Mar 04 '18 at 20:35
@Onyambu I did try encoding("utf-8") but dont work – Rodrigo B Mar 04 '18 at 20:42
You did not answer what do you get when you do `Encoding(mach_text)`? – Onyambu Mar 04 '18 at 20:44
@Onyambu "unknown" and "UTF-8" – Rodrigo B Mar 04 '18 at 20:47
`iconv(x,"utf-8","latin1","")`? – Onyambu Mar 04 '18 at 20:48
@Onyambu I did run iconv(x,"utf-8","latin1","") and : "unknown" and "UTF-8" again. – Rodrigo B Mar 04 '18 at 20:50
No this cannot give you what you just said. Try it again. You ran the wrong line. `icov` will never return an encoding – Onyambu Mar 04 '18 at 20:52
@Onyambu, Sorry, I did run again and give me (extract): [9999] "RT deadmantetris: Una mujer fantastica" [10000] "RT biobio: Estreno en TV de \"Una Mujer fantastica" – Rodrigo B Mar 04 '18 at 20:58
if i run encoding(mach_text), "unknown" and "latin1" – Rodrigo B Mar 04 '18 at 20:59
Is that what you needed? – Onyambu Mar 04 '18 at 21:02
@Onyambu Yes!! great! Thanks for your time and patient! – Rodrigo B Mar 04 '18 at 21:05
