Thank you Professor: After reading in the file this is what I see: > file.label [1] "EXAMPLE 1 â vs a.xls"
charToRaw(file.label) [1] 45 58 41 4d 50 4c 45 20 31 20 c3 a2 20 76 73 20 61 2e 78 6c 73 > Encoding(file.label) [1] "UTF-8" > Encoding(paste("diagnostic â vs a ", file.label, ".jpg", sep = "")) [1] "UTF-8" But look what happens after I run your example: > charToRaw(file.label) [1] 45 58 41 4d 50 4c 45 20 31 20 e2 20 76 73 20 61 2e 78 6c 73 (after) [1] 45 58 41 4d 50 4c 45 20 31 20 c3 a2 20 76 73 20 61 2e 78 6c 73 (before) The file label appears on the screen as it does above both times, but clearly charToRaw() shows that the coding for â has changed from the unexpected c3 a2, to the desired e2. After running your example I now observe > Encoding(file.label) [1] "latin1" Again, thank you for your help. Charles Annis, P.E.

Cc: r-help@r-project.org Subject: RE: [R] trouble with character \u00e2 That also works without a hitch on my box, even in vanilla 2.7.2. What exactly is in file.label as given by charToRaw(file.label) Encoding(file.label) ? It should be in UTF-8, and so should paste("diagnostic â vs a ", file.label, ".jpg", sep = "") It looks like the latter is not being treated as UTF-8 on your system (see what Encoding() says on its value).
