  import std/unicode
  
  let str = “你好/hi”
  
  for c in str.runes():
    case c:
      of '/':  # compile error here, since c is type of distinct RuneImpl
       echo " '/' found"
       break
  Run

  Please stop repeatedly creating new threads and deleting old ones. The forum has edit functionality. As for your question, use the utf8 iterator to iterate over runes as strings:

  import std/unicode
  
  let str = "你好/hi"
  
  for c in str.utf8():
    case c
    of "/":
      echo " '/' found"
      break
  Run

  thanks a lot ;-)

  There is always a problem with the code snippet render. I have to use pictures, and then it becomes normal again.

  You don't have to create new threads though, you can press "Edit" to edit your post.

  You can also use:

  import std/unicode
  
  let str = "你好/hi"
  
  for c in str.runes():
    case c:
      of Rune('/'):
        echo " '/' found"
        break
      else:
        discard
  Run

  Also, you have to add some text to the post in addition to the code snippet, or it'll not be rendered.
