希望删除下面示例文本中 {} 之间的“#”字符

我尝试了什么？

\{[#].*\}

您可以使用以下模式:

(?:\{|(?<!^)\G)[^#\r\n]*\K#+(?=.*\})

..并用空字符串替换。

(?:             # Beginning of a non-capturing group.
    \{          # Matches the character '{' literally.
    |           # Alternation (OR).
    (?<!^)\G    # Asserts position at the end of the previous match.
)               # End of the non-capturing group.
[^#\r\n]*       # Matches zero or more characters other than '#' or line breaks.
\K              # Resets the starting point of the match (only include what comes next).
#+              # Matches one or more '#' characters.
(?=.*\})        # A positive Lookahead to make sure the `}` character exists.
