asp createTextFile生成文本文件支持utf8（asscii）这都可以？

文章摘要

这篇文章介绍了三个自定义函数及其在文件操作中的应用，重点在于错误处理和路径管理。首先，`createTextFile`函数负责打开或创建文件并写入内容，支持多种编码方式，并在错误时调用`echoErr`函数显示错误提示。其次，`createFolder`函数用于创建文件夹，处理路径替换和错误检查。最后，`echoErr`函数用于显示错误信息，并通过CSS样式美化错误提示，包含错误编号、描述、位置等细节。文章整体围绕自定义函数的实现及其在实际开发中的应用展开，旨在提供一种高效的文件操作解决方案。
