easy-u8g2-font-generate-tools's Issues

在使用（包括您的）各种工具时，发现我的UTF8中文和中英文混合字符串出现中间空白

使用的硬件环境：STM32+HAL
使用的U8G2版本：
olikraus/u8g2@3e86287
使用的生成字体(请删除txt后缀)：
SarasaMonoSC-Regular.ttf.txt

使用的代码：

    u8g2_DrawUTF8(&u8g2, 0, 30, "距1234567");
    u8g2_DrawUTF8(&u8g2, 0, 62, "倾890.123");

得到的现象：

应该得到的现象：
数字和中文应该不间断，但实际中间有空白。

排除的问题：
在使用u8g2官方内置的字体如u8g2_font_wqy12_t_gb2312a的显示正常

可以认定是字符串和u8g2不兼容，但具体是什么导致的，只有三个可能性，1. 文字字体与您U8g2工具不兼容，2. 您U8g2工具和最新版本代码不匹配，3. 文字字体和最新版本代码不匹配。

请问字体DPI怎么填?
