Flutter iOS运行报错：Unicode Normalization not appropriate for ASCII-8BIT

在iOS上运行Flutter应用时触发以下CocoaPods错误，应用可正常构建，仅运行时出错：

        Consider adding the following to ~/.profile:

已在~/.profile和~/.zshrc中添加export LANG=en_US.UTF-8，执行locale命令显示编码配置正常：

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

在iOS目录执行pod install可正常完成，但运行Flutter应用时仍触发上述错误。

已完成以下排查步骤，排除常见问题：

• Podfile中已添加source 'https://cdn.cocoapods.org/'
• 可正常执行pod install无异常
• locale命令显示Unicode编码配置正确
• 已在~/.profile和~/.zshrc中配置正确的Unicode编码
• which ruby命令指向/usr/local/opt/ruby/bin/ruby，路径正常
• 已完全重装CocoaPods，但问题仍未解决

恳请提供有效的解决方案。
