Minion Pro字体仅部分生效求助：fontspec配置无效问题排查

我之前配置Minion Pro字体时也踩过类似的坑，咱们一步步拆解问题并解决：

核心问题1：系列名不匹配 #

你定义FontFace = {c}{n}{*-Cn}时，第一个参数c是字体系列名，但你在\cnseries里用的是\fontseries{cn}\selectfont——这里的系列名写成了cn，和定义的c不匹配，fontspec自然找不到对应的字体变体。

核心问题2：SizeFeatures覆盖了变体配置 #

你当前的SizeFeatures直接指定了单一字体文件（比如MinionPro-Capt.otf），这会让对应字号范围内的主字体强制变成这个文件，但该文件不包含condensed、medium等变体，导致你在这些字号下调用变体时失效。

核心问题3：文件名拼写错误 #

比如你注释掉的*MediumIt少了连字符，应该是*-MediumIt，拼写错误会导致fontspec找不到字体文件。

修正后的完整配置示例 #

  FontFace = {sb}{it}{*-SemiboldIt},
  % Condensed系列（含斜体）
  FontFace = {c}{n}{*-Cn},
  FontFace = {c}{it}{*-CnIt},
  % Semibold Condensed系列
  FontFace = {sbc}{n}{*-SemiboldCn},
  FontFace = {sbc}{it}{*-SemiboldCnIt},
  % Medium系列
  FontFace = {md}{n}{*-Medium},
  FontFace = {md}{it}{*-MediumIt},
  % 字号特征：为每个字号段配置全变体
  SizeFeatures = {

     FontFace = {c}{it}{*-CnIt},
     FontFace = {md}{n}{*-Medium},
     FontFace = {md}{it}{*-MediumIt}

    {Size = 13.01-19.91,
     UprightFont = {*-Subh},
     ItalicFont = {*-SubhIt},
     BoldFont = {*-BoldSubh},
     BoldItalicFont = {*-BoldSubhIt},
     FontFace = {sb}{n}{*-SemiboldSubh},
     FontFace = {sb}{it}{*-SemiboldSubhIt},
     FontFace = {c}{n}{*-SubhCn},
     FontFace = {c}{it}{*-SubhCnIt},
     FontFace = {md}{n}{*-MediumSubh},
     FontFace = {md}{it}{*-MediumSubhIt}
    },
    {Size = 19.91-,
     UprightFont = {*-Disp},

     FontFace = {md}{it}{*-MediumDispIt}

额外注意事项 #

1. 验证字体文件名：确保你的Minion Pro字体文件实际名称和配置中的一致（比如有些版本的condensed字体可能叫MinionPro-Condensed而非MinionPro-Cn，需要对应修改配置）。
2. 字体路径：如果字体未安装在系统字体目录，需要用Path = {/path/to/fonts/}参数指定字体文件所在路径。
