我遇到模块UnicodeDecodeError错误FileAdmin（包含在Flask-AdminFlask库中）：
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 5: ordinal not in range(128)
每当我创建名称中包含非ASCII字符的目录（例如très）时，都会出现该错误。
我认为关键是要添加UTF-8编码：
# -*- coding: utf-8 -*-
但是在哪里（哪些文件？）以及如何在其中处理FileAdmin module呢？我不清楚。
编辑以下@PaoloCasciello请求，在错误回溯下方找到

之所以发生这种情况，是因为Pythonos.walkdir在使用ascii路径调用时以ASCII返回文件名。
因此，在初始化FileAdmin时，请确保将基本路径作为unicode字符串传递：
admin.add_view(unicode(path), '/files/', name='Files')
最新的Flask-Admin已修复此问题-FileAdmin将在内部强制使用unicode作为路径。
