fmt ff font lf 里面的 LANGID 是什么意思
lf - 選字體的邏輯，用到語言字符集
font 從lf里來的而已
ff 是 family， 不是具體的一個字體，是一類，有相同的as des cellline...
fmt 是字串的格式？ ？？？ 因為宋體可以表示很多語言，所以，還是fmt原來的默認的好。
那么，為什么 區域改為 臺灣或英文到中文，就解決問題了呢？ 難道是 ff 搞錯了導致的嗎
因為fmt不應該影響布局的啊。

如果是ff出錯導致id，為什么有的cell對有的錯，大部分對
ff如果初始化失敗，然后 r 的數值會？
ff失敗的結果，不穩定嗎，否則很難評價
1. 有的不可見了， r的范圍完全超出
2. 有的 Y稍微偏移了。
3. 正常的又怎么回事 跟偏移的同時存在
