Weird Unicode involved output

[pwang2]

The space before the first element will output something nonsense.

> styler::style_text('a <- c( "TΔ", "An")')
a <- c("TΔ",""An")
> styler::style_text('a <- c("TΔ", "An")')
a <- c("TΔ", "An")

The parsed data is nothing wrong.

Thank @pwang2. Are you on windows? Which {styler} and R version do you have?

[lorenzwalthert]

On macOS with {styler} dev and R 4.1, I get

styler::style_text('a <- c( "TΔ", "An")')
#> a <- c("TΔ", "An")

Could be a 3.x thing.

Can you install the dev version from GitHub and tell me if the error persists? We recently added stronger guarantees in #895 that should result in an error for your case.

[pwang2]

Looks like the same.

[lorenzwalthert]

Ok. Which R terminal? Linux usually does not have problems with unicode characters. Maybe it's also a display issue? Can you write to file and open the output with a text editor? e.g.

[pwang2]

Good call. A little complex with the terminal at my side. I was using Windows Terminal + git bash(Cygwin) then SSH to a remote machine. Let me try a more direct one.

[lorenzwalthert]

tmp <- tempfile(fileext = ".R")
writeLines('a <- c( "TΔ", "An")', tmp)
styler::style_file(tmp)
readLines(tmp) # and open in text editor.

Can you try this?

[lorenzwalthert]

This looks correct to me. What do you think?

[lorenzwalthert]

but you got an error, which is interesting.
