Additional information

Observations:

X

type - beep, shows space in its place
at prompt - paste from clipboard as single symbol - crash without message
at prompt - paste from clipboard in the middle of string - skipped
at prompt - Alt+Numpad7 - beep, shows space in its place
echo from prompt - muffled/short beep, shows no space in its place
echo from file - muffled/short beep, shows no space in its place
dir at volume label that has it - muffled/short beep, shows no space in its place

Staging

type - beep, shows no space in its place
at prompt - Alt+Numpad7 - beep, shows no space in its place, beeps also on each subsequent character entered
at prompt - paste from clipboard - string cut at its place (so nothing gets pasted if it's the only symbol)
echo from prompt - beep, shows no space in its place
echo from file - no beep, shows no space in its place
dir at volume label that has it - beep, shows no space in its place

86Box PC DOS 7.00

at prompt - Alt+Numpad7 - no beep, shows ^G
echo from prompt - short beep, shows no space in its place
echo from file - short beep, shows no space in its place
type - short beep, shows no space in its place
dir at volume label that has it - short beep, shows no space in its place

Not tested:
dir of filename/directory that has that symbol
hardware PC

What I think should be improved:

• Paste from host clipboard to do the same as as Alt+Numpad7
  • do not crash at paste from clipboard as single symbol
  • do not skip at paste from clipboard in the middle of string
• To beep in the same way in all cases
  • echo/dir of volume label to have the same beep as type/prompt - not the current muffled/short one
