gslc_FontSet fail to add vlw font file from SPIFFTS

[JoeHo8051]

Describe the bug

I put my vlw file into spiffs, and I check the file do exist in the SPIFFS area.
It seems it failed to load the font , I saw the serial return "Font file cairomedium16.vlw not found! " when I enter the page using that font.

Here is my code:

if (!gslc_Init(&m_gui,&m_drv,m_asPage,MAX_PAGE,m_asFont,MAX_FONT)) { return; }

if (!SPIFFS.begin(true)) {
return;
}

// ------------------------------------------------
// Load Fonts
// ------------------------------------------------
//<Load_Fonts !Start!>
if (!gslc_FontSet(&m_gui,E_BUILTIN10X16,GSLC_FONTREF_PTR,NULL,2)) { return; }
if (!gslc_FontSet(&m_gui,E_BUILTIN15X24,GSLC_FONTREF_PTR,NULL,3)) { return; }
if (!gslc_FontSet(&m_gui,E_BUILTIN5X8,GSLC_FONTREF_PTR,NULL,1)) { return; }
if (!gslc_FontSet(&m_gui,E_CAIROBOLD16,GSLC_FONTREF_FNAME,CAIROBOLD16_VLW,16)) { return; }
gslc_FontSetMode(&m_gui, E_CAIROBOLD16, GSLC_FONTREF_MODE_1);

if (!gslc_FontSet(&m_gui,E_CAIROMEDIUM16,GSLC_FONTREF_FNAME,"cairomedium16.vlw",16)) { return; }

@JoeHo8051 Post a zip file of a test project with just one text field using your font and include the full project folder with data folder and your cairomedium16.vlw
and I will take a look.
Also, If you used the builder then include your modified GUIsliceBuilder/templates/builder_fonts.json

@JoeHo8051 By the way here is a simple stand alone program without GUIslice or TFT_eSPI to list spiffs file names to serial output.
