In some outputs from ChatGPT, writing number ranges like 1~3개 or 4~6개 can lead to unexpected strikethrough formatting.
Specifically, when there are no spaces around the ~, parts of the text — like “3개 혹은 4” — sometimes appear with a strikethrough applied.
The exact cause isn’t clear, but it seems related to how Markdown interprets tilde symbols.
Normally, a double tilde ~~ triggers strikethrough formatting, so perhaps missing spaces or internal formatting quirks are causing this unintended effect.
This makes some parts of the text confusing to read, especially in languages like Korean or Japanese where ~ is commonly used for ranges.
It would be great if future versions of ChatGPT could handle ~ usage more safely — either by automatically adding spaces around tildes or by adjusting how Markdown rules are applied in these cases.
