When ChatGPT outputs number ranges using tildes without spaces (e.g., 1~3, 4~6), the markdown parser renders part of the phrase as strikethrough (e.g., 3개 혹은 4), which causes confusion.
This happens because the tilde (~) is interpreted as the start/end of strikethrough formatting.
Even when users explicitly instruct the model to add spaces around tildes (1 ~ 3), this behavior is not consistently followed.
Suggestion:
Ensure GPT inserts spaces around tildes in number ranges (e.g., 1 ~ 3)
Or escape tildes automatically when used in non-formatting contexts
Or allow users to disable markdown formatting entirely in certain contexts
Even when users explicitly set memory instructions (e.g., “Always add spaces around tildes”),
ChatGPT often fails to consistently follow them in output.
This reduces trust in the memory feature and creates repeated friction for users with specific formatting needs.
