我有一个有点难以解释的问题。我将 devsniper 的应用程序“客户”作为基础，为本地计算机商店启动 POS 系统。原始应用程序使用 MySQL，但是此应用程序使用我客户的原始数据至关重要。所以我有两个选择：

1）我可以将 SQLite 数据库迁移到 MySQL 数据库
2）我可以修改程序以使用 SQLite 数据库（首选）

但是，每当我尝试打开客户页面时，都会得到以下信息：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128)

我不知道从哪里开始详细说明我的问题，因为没有详细说明导致此问题的确切原因，但是我将从追溯开始。

发布解决方案编辑：

问题出在这里：

${items.pager(format="$link_previous ~2~ $link_next", 
                  symbol_previous="«", 
                  symbol_next="»",
                  link_attr=link_attr,
                  curpage_attr=curpage_attr,
                  dotdot_attr=dotdot_attr,
                  onclick="$('.list-partial').load('%s'); return false;")}

出于某种原因，“»”字符及其对应字符正在抛出错误。我只是将它们更改为标准的 ascii 字符，一切都是金色的。

是的，你关于放慢迈克尔的速度是对的——这是一个非常简单的错误。在 uiHelpers.html 中有一个 unicode 字符“»”，由于某种原因导致了问题。只需将其更改为“>”，它就是金色的。这是一个很好的教训，可以更仔细地阅读回溯，感谢您的反馈。
