使用python或javascrip将Hershey-font.jhf解析为json

Question

我一直在网上寻找解决办法，但我没有发现任何在我能力范围内的东西。如何使用python或javascript将这些Hershey-Font.jhf文件emergent.unpythonic.net/software/hershey转换为JSON。创造类似于：

[
    {
        asciival:26,
        points:[[5,-5],[4,7,8],[6,8,7]]
    },
    {
        asciival:27,
        points:[[5,-3],[4,7,33],[6,32,7]]
    },
(…)
]

我知道有一个question here，但这不足以让我理解这个系统。在

我已经找到了肖恩在评论中指出的描述。在

As an example consider the 8th symbol 8 9MWOMOV RUMUV ROQUQ
It has 9 coordinate pairs (this includes the left and right position).
The left position is 'M' - 'R' = -5
The right position is 'W' - 'R' = 5
The first coordinate is "OM" = (-3,-5)
The second coordinate is "OV" = (-3,4)
Raise the pen " R"
Move to "UM" = (3,-5)
Draw to "UV" = (3,4)
Raise the pen " R"
Move to "OQ" = (-3,-1)
Draw to "UQ" = (3,-1)
Drawing this out on a piece of paper will reveal it represents an 'H'.>

我试着弄明白，但价值观从何而来？
例如，为什么是UM（3，-5）？在

我找到了this java class

坐标是连续的字符对。要将它们转换成数字，您需要从每个字符中减去相当于字符“R”=82的ascii。在您的示例中，“UM”转换为（3，-5），因为U是ascii码85。减去82（‘R’）得到3。M是ascii码77，减去82得到-5。在
