How do I make a specific letter of a string uppercase in Julia?

How do I make a specific letter of a string uppercase, and not changing any of the other letters?

My example:

"this works" -> "this woRks" //Change made to letter 7
"this works" -> "this wOrks" //Change made to letter 6
"this works" -> "This works" //Change made to letter 1

My system uses characters with a UTF-8 encoding, so it needs to support uppercase for UTF-8 characters and not just ascii.

Solution

  • Unoptimized one-liner :)

    julia> s = "this is a lowercase string"
"this is a lowercase string"

julia> String([i == 4 ? uppercase(c) : c for (i, c) in enumerate(s)])
"thiS is a lowercase string"
