7854 :: char type: echo ASCII code for 'space' and 'single quote'

  Character type "char":

  • how to print ASCII code for 'space'
  • 'single quote' character surrounded by single quotes (it seems to be an exception)?

  echo '\n'.repr    # prints ASCII code 10 (enter)
  echo ' '.repr     # prints ' '   - but how to print ASCII code (space)?
  echo '\t'.repr    # prints ASCII code 10 (tab)
  echo '\''         # prints '     - but how to print ''' ?
  Run

  Actually single quote works fine:

  echo '\''         # prints as expected     '
  echo '\''.repr    # prints as expected   '''
  Run

  However, how to print ASCII code?

  to print the ASCII code you need to convert it to an integer type:

  import strutils # for toHex
  echo ord('\'')
  echo int('\'')
  echo toHex(ord('\'')) # prints as hexadecimal
  Run

  Note that repr is mostly meant for debug purposes, so I wouldn't rely on it to get a specific output.
