Questions re: custom fonts

Hello, I'm trying to create a small, custom 3x5 font and am having issues getting it to display correctly. I'm using a 16x32 LED matrix and Particle photon.

I only need a small subset of the 0x20 - 0x7F character set. I made custom bitmaps in an spreadsheet below:

Below is my hard-coded bitmap and descriptor. Since I only need a few characters, I figured I can make the unused characters blank. (note: added comments in the bitmap for clarity, I remove them when compiling)

Can the bitmap have any start and end character or do I have define all the characters between 0x20 and 0x7F?

Thanks in advance and appreciate any insight you might have!

#ifdef TESTFONT
const uint8_t testBitmaps[] =
{
	0x20, 0x5B,	// Start Character, End Character
	0x00,		//	' '
	0x00,		//	'!'

How to make a swedish font?

In sweden we has å ä ö Å Ä Ö charracters and i see in the readme for this repository its says "The free TheDotFactory Windows program is recommended for creating font data compatible with the Adafruit_mfGFX library.".

So i downloaded it and maked a font like i whanted it but the Descriptors is a two dimension array like this:

`const FontDescriptor SWE_8ptDescriptors[] = 
{
	{1, 0}, 		// ! 
	{3, 15}, 		// " `

and in the fonts.pp its looks like:

const FontDescriptor arial_8ptDescriptors[] =
{
	{2, 10, 0},
	{1, 10, 10},

any idea how to make my swedish font to work?

Please replace #define swap()

That macro makes the use of several std:: classes rather difficult.

This rather simple test throws a load of errors all in std::vector

#include "Adafruit_mfGFX/Adafruit_mfGFX.h"
#include <vector>
void setup() { }
void loop() { }

Sure #undef swap does fix that, but still ;-)
