例如我想使用USB图标，Unicode ID 为 0xf287，文字输入框中该怎么选择？

在 https://littlevgl.com/ttf-font-to-c-array 地址生成字体，配置好各选项后点击“convert”会出现卡一会然后就刷新的页面，各参数都没有了，请问这是什么情况？

移植用老版本littlevGL,移植成功后显示汉子成功；通过在线取模（https://littlevgl.com/ttf-font-to-c-array-old）。之前版本字体样式
lv_font_t chinese1_m1_font =
{
    .unicode_first = 19968,    /*First Unicode letter in this font*/
    .unicode_last = 40959,    /*Last Unicode letter in this font*/
    .h_px = 25,                /*Font height in pixels*/
    .glyph_bitmap = chinese1_m1_font_glyph_bitmap,    /*Bitmap of glyphs*/
    .glyph_dsc = chinese1_m1_font_glyph_dsc,        /*Description of glyphs*/
    //.glyph_cnt = 18,            /*Number of glyphs in the font*/
    .unicode_list = chinese1_m1_font_unicode_list,    /*List of unicode characters*/
    .get_bitmap = lv_font_get_bitmap_sparse,    /*Function pointer to get glyph's bitmap*/
    .get_width = lv_font_get_width_sparse,    /*Function pointer to get glyph's width*/
#if USE_CHINESE1_M1_FONT == 1
    .bpp = 1,                /*Bit per pixel*/
#elif USE_CHINESE1_M1_FONT == 2
    .bpp = 2,                /*Bit per pixel*/
#elif USE_CHINESE1_M1_FONT == 4
    .bpp = 4,                /*Bit per pixel*/
#elif USE_CHINESE1_M1_FONT == 8
    .bpp = 8,                /*Bit per pixel*/
#endif
    //.monospace = 0,                /*Fix width (0: if not used)*/
    .next_page = NULL,        /*Pointer to a font extension*/
};

移植最先版本littlevGL 6.0.0后，发现字体结构改变了，请教需要怎么修改？
typedef struct _lv_font_struct
{
    /** Get a glyph's  descriptor from a font*/
    bool (*get_glyph_dsc)(const struct _lv_font_struct *, lv_font_glyph_dsc_t *, uint32_t letter, uint32_t letter_next);

    /** Get a glyph's bitmap from a font*/
    const uint8_t * (*get_glyph_bitmap)(const struct _lv_font_struct *, uint32_t);

    /*Pointer to the font in a font pack (must have the same line height)*/
    uint8_t line_height;      /**< The real line height where any text fits*/
    uint8_t base_line;        /**< Base line measured from the top of the line_height*/
    void * dsc;               /**< Store implementation specific data here*/
#if LV_USE_USER_DATA
    lv_font_user_data_t user_data; /**< Custom user data for font. */
#endif
} lv_font_t;
