I am still/again strucling with getting local characters to work with your weatherstation.

It seems the font-generator does not include æøå or other special charecters. Could this easyli by implemented or is it left out by intension?

If the font size is too big the size of the array that holds the character data cannot be stored anymore as a byte in the jump table. As a result, characters are only displayed partially (reproduceable e.g. by choosing Dialog, Plain, 64).

Best would be to allow such bigger sizes (e.g. by storing the size as two bytes similar to the jump address) or at least show a warning in the web tool, if the chosen font produces too big character arrays,

The GFXfont struct has last_char as 0x7E (tilde)
But the bitmap has no entry for 0x7E
And the glyph has no entry for 0x7E

If the Adafruit_GFX application prints a tilde, the screen is corrupted.

fontConverterV2.java and fontConverterV3.java define END_CHAR=256 i.e. last_char +1
If you follow the same style for fontConverterGFX.java you could: END_CHAR=127 i.e. tilde+1
private static final int END_CHAR = 127;
and last_char as 126 (tilde) in the GFXfont struct
builder.append(String.format("0x%02X, ", (byte) (END_CHAR - 1)));

All three Font formats specify FIRST_CHAR and END_CHAR

The Web Application is very convenient for Adafruit_GFX users

It would be useful addition to use variables for START_CHAR and END_CHAR configured by the Web app.
Then the user could produce subsets of any Font e.g. 0-9

hello, how can i add ÄÖÜ in ArialRoundedMtBold_14.h ? i can't find a way.

Hi,
Sorry, I'm new to openshift but as this is a nodejs app, can I run this app locally with just nodejs ?
I installed express and fs but seems to need openshift.
node server.js bring me a openshift page ?
The reason I need this is I need to convert a licensed Font that it's not on font list of course.

Any tip would be appreciated.

Since fonts in large point sizes gobble up precious resource space...

Feature Request for the Font Converter

It would be nice to have UI entry fields added for ASCII Start Value and ASCII End Value providing a way to filter the output of characters in the converted font. These two new entry fields will default to the current hard-coded values of 32 and 255 respectively.

For example, filtering down to ASCII 45 to 57 would include just the numbers, a minus sign, period and slash. This would also allow limiting a full font to the upper limit of ASCII 127 to save space.

It appears that OLEDDisplay::drawStringInternal() will support this change without changes.

I'd submit a PR but that likely would take me a while to get this done properly.

Thanks in advance.
