步骤1：为单行带♪的文本末尾添加♪ #

打开Notepad++查找替换窗口（快捷键Ctrl+H），勾选「正则表达式」，取消「.匹配换行符」：

• 查找内容：^♪(.*)(?<!♪)$
• 替换为：♪$1 ♪

规则说明：

• ^♪：精准匹配以♪开头的行
• (.*)：捕获该行♪之后的所有内容
• (?<!♪)$：负向断言，确保行尾未添加过♪，避免重复操作
• $1：引用捕获的文本，末尾追加 ♪

步骤2：为双行带♪的文本末尾添加♪ #

保持正则模式不变：

• 查找内容：^♪(.*)\r\n([^\n]+)(?<!♪)$
• 替换为：♪$1\r\n$2 ♪

规则说明：

• ^♪(.*)\r\n：匹配以♪开头的第一行，捕获行内内容并匹配Windows格式换行符
• ([^\n]+)：捕获第二行的所有内容（不含换行符）
• (?<!♪)$：确保第二行末尾无♪
• $1和$2分别引用两行的捕获内容，仅在第二行末尾追加 ♪
