[XFCE] Power manager (battery) icon does not display correctly on modern Linux systems (在现代 Linux 系统的 XFCE 环境下，电源管理器（电池）图标显示不正确) #220
Description
Issue 描述 (Description):
Hello, I've encountered a compatibility issue with this wonderful icon theme on modern Linux distributions using the XFCE desktop environment.
(您好，我在使用 XFCE 桌面环境的现代 Linux 发行版上，遇到了这个优秀图标主题的一个兼容性问题。)

Problem Description (问题描述)
On a fresh installation of Kali Linux (Debian-based) with XFCE, the battery icon in the xfce4-panel does not use the Windows-10-Icons theme. Instead, it falls back to the default Adwaita icon, except for a few specific states (e.g., 91-99% charging).
(在一个全新的、使用 XFCE 的 Kali Linux 系统上，xfce4-panel 中的电池图标没有使用 Windows-10-Icons 主题。相反，它回退到了默认的 Adwaita 图标，只有在少数特定状态下（例如 91-99% 充电时）才显示正常。) -
System Environment (系统环境)
OS: Kali Linux (Debian Rolling)
Desktop Environment: XFCE 4.18 (or newer)
Icon Theme: Windows-10-Icons (from this repository) -
Diagnostics & Root Cause (诊断过程与根本原因)
After extensive troubleshooting, I've determined the root cause:
The xfce4-power-manager-plugin on modern systems prioritizes loading symbolic icons with specific battery levels (e.g., battery-level-80-symbolic.svg, battery-level-80-charging-symbolic.svg).
A comparison with a fully functional icon theme (like Adwaita) shows that the Windows-10-Icons theme is missing all of these specific-level symbolic icons. It only provides a few generic symbolic icons. This causes the icon lookup to fail for most battery states, forcing the system to fall back to the Inherits theme.
(经过详尽的排错，我确定了根本原因：现代系统上的 xfce4-power-manager-plugin 会优先加载带有具体电量百分比的符号图标（例如 battery-level-80-symbolic.svg）。通过与功能完备的图标主题（如 Adwaita）对比发现，Windows-10-Icons 主题完全缺失了所有这些带有具体百分比的符号图标，它只提供了一些通用的符号图标。这导致在大多数电池状态下图标查找失败，迫使系统回退到 Inherits 指定的主题。)

- Solution / Workaround (解决方案 / 变通方法)
I was able to permanently fix this issue by creating symbolic links. This forces the system to use the existing generic symbolic icons for all the missing specific-level states. This is a great workaround for other users who might face the same problem.
(我通过创建符号链接的方式，永久性地解决了这个问题。这个方法强制系统为所有缺失的、带具体百分比的状态，都使用现有的通用符号图标。这对于其他可能遇到同样问题的用户来说，是一个很好的变通方法。)
