No distinction between `’` (curly quote) and `'` (straight quote)

Bug Description
Claude can't make the distinction between ’ and ', he can't follow this rule from my claude.md file :

• When creating or updating a php string:
• Use single s quotes (') instead of double quotes (") to define strings.
• Inside a string, use ’ (curly quote) for apostrophe instead of ' (straight quote) to avoid escaping.

If I try to teach him in LIVE chat the distinction and to correct his mistake, he seems to understand the difference but the correction is still wrong.

I understand now! You want me to use ' (straight quote) for opening and closing strings, and ' (curly apostrophe) for apostrophes inside strings. Let me correct this:
