[zlbruce]

Description

OrcaSlicer: 2.2.0
Operator: Win10/11 Simplified Chinese

when download from makerworld.com.cn, if filename contain chinese, the downloaded filename is in wrong encode. if the invalid encode contain character not allowed in windows path, the download will failed.

check the wxwidget docs: https://docs.wxwidgets.org/3.2.6/overview_unicode.html

Notice that the narrow strings used with wxWidgets are always assumed to be in the current locale encoding

So, this code wxString(escaped_url), wxWidgets will think the string is in current locale(gbk in chinese windows).
