在Fedora43、gnome下可能会替代一切字体

[Mesdon10]

包括但不限于微信默认字体，chrome的标签页、收藏和历史的字体。
下载的是本字体的.zip压缩包（maple.zip），解压到了/home/username/.local/share/fonts/maple下进行使用。终端和vscode等均可正常替换。
但上述问题其实很可能未必是字体导致的，因为我在安装系统后曾操作ibus等试图将自带的中文输入法修改为本字体，但发现间距过大不适合后作罢，然而当时由于没有设置备份快照等原因已难以复现。
通过修改~/.config/fontconfig/fonts.conf文件为：

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>

  <!-- 策略一：当系统请求通用字体族时，明确拒绝 Maple -->
  <selectfont>
    <rejectfont>
      <!-- 这里列出系统请求通用界面字体时的场景 -->
      <pattern>
        <patelt name="family"><string>sans-serif</string></patelt>
        <patelt name="family"><string>Maple Mono NF CN</string></patelt>
      </pattern>
      <pattern>
        <patelt name="family"><string>serif</string></patelt>
        <patelt name="family"><string>Maple Mono NF CN</string></patelt>
      </pattern>
      <pattern>
        <patelt name="family"><string>system-ui</string></patelt>
        <patelt name="family"><string>Maple Mono NF CN</string></patelt>
      </pattern>
    </rejectfont>
  </selectfont>

  <!-- 策略二：强力绑定默认中文字体 (双重保险) -->
  <!-- 当任何程序请求 sans-serif 时，首选 Noto Sans CJK SC -->
  <match target="pattern">
    <test qual="any" name="family">
      <string>sans-serif</string>
    </test>
    <edit name="family" mode="prepend" binding="strong">
      <string>Noto Sans CJK SC</string>
    </edit>
  </match>

  <!-- 当任何程序请求 system-ui 时，首选 Noto Sans CJK SC -->
  <match target="pattern">
    <test qual="any" name="family">
      <string>system-ui</string>
    </test>
    <edit name="family" mode="prepend" binding="strong">
      <string>Noto Sans CJK SC</string>
    </edit>
  </match>

</fontconfig>

后成功修改了微信字体，但chrome标签页等字体仍未修改（我确定chrome内部设置字体里没有maple mono nf cn，重新刷新字体缓存、删除chrome缓存后仍没有修改成功）。
删除本字体后情况恢复。
考虑到可能是fedora43的bug或其他原因，因此请字体开发者不要过分在意本issue，很可能是本人技术能力或者其他原因导致的。
现在仍在排查原因中。

在 NixOS 上的 flatpak 程序也出现了这种情况，sans 和 monospace 有变化。在 fontconfig 根本没有配置，删除字体后并重装 flatpak 软件或清除对应软件 fontconfig 缓存后正常， flatpak/flatpak#1563
安装 maple-mono 任何 CN 都会有这种情况，安装 maple-mono 不带 CN 正常使用

这可能是上游或字体内的配置有问题，如果有人在flatpak复现请转为issue，我这里每次都能复现

[xuanplus]

我这里好像没问题？
