带有指向const数组的指针的struct怎么使用

我正在为像ST735这样的所有LCD驱动程序编写一个程序库。库正在工作，一切都还好，但是我有一个函数来设置文本的字体：ValueStCuffType（无符号char字体，unChar char字体，unchar char funw，unchar char间距ECC…）。Edchar * FuntRay.UnSchar Chan-Funw；未签名的Char Fulth.Ec..字体；但XC8不允许我这样做。结构中只有一个指针，不是一个变量或可变大小数组（XC8中不允许）。我只想知道是否有一种方法，如果不是，我只会按原样使用函数。

    I'm writing a library for all the LCD drivers like st7735. Library is working and all is ok, but i have a function to set the font of text:

void setCustomFont(unsigned char *font, unsigned char fontH, unsigned char fontW,unsigned char spacing ecc..)
I would like to delcare a typedef struct that contains all of this data like

typedef struct font_ {
const unsigned char *fontarray;
unsigned char fontW;
unsigned char fontH;
ecc..
}font;

But XC8 doesn't let me do this. There is just a pointer in the struct, not a variable or and variable size array(not allowed in xc8).
I just want to know if there is a way, if not i will just use the function as is.
