LoadFont / LoadFontEx fail with "Character size is bigger than expected font size"

[almostobvious]

So I am trying to use a TTF. I followed the TTF example here so code looks like this:

// somewhere in declarations
Font defaultFont;
. . .
// font load
	defaultFont = LoadFontEx("res/fonts/digital-7.ttf", 32, 0, 250);
. . .
// then later I use it
   DrawTextEx(defaultFont, text, (Vector2){ x,y }, textSz, 2, textColor);

When I run the app, it still uses built-in font (not my ttf) and following messages are printed:

INFO: FILEIO: [res/fonts/digital-7.ttf] File loaded successfully
WARNING: FONT: Character [0x00000021] size is bigger than expected font size
WARNING: FONT: Character [0x00000024] size is bigger than expected font size

WARNING: FONT: Character [0x00000031] size is bigger than expected font size
WARNING: FONT: Character [0x00000032] size is bigger than expected font size

... all numbers between 32 and 7c are printed as above and below ...

WARNING: FONT: Character [0x0000007c] size is bigger than expected font size
WARNING: FONT: Character [0x0000007d] size is bigger than expected font size
WARNING: FONT: Character [0x000000a9] size is bigger than expected font size
INFO: FONT: Data loaded successfully (32 pixel size | 250 glyphs)

I've tried a whole bunch of fonts ttf and odf, including monaspace etc I get same results.

What am I doing wrong? How do I load a font to use it for DrawText(Ex)?

Ok, I think I understand - LoadFont(Ex) can only be called after InitWindow.

Not sure about error messages here - maybe LoadFont should check that InitWindow is done are report a clearer error (e.g. "LoadFont failed. Call InitWindow before calling LoadFont")?
