@Blawnode: Hello again and thanks once again for taking interest in implementing this format.
I'd like to help you fix whatever problem or bug you seem to have with loading the fonts here but I cannot simulate the error you are describing.
This is what I get if I download ?font=contra and display it "as is" in hexadecimal mode - https://i.ibb.co/mhVWSh3/contra-hex.png
(displayed in Total Commander for Win32 platform)
Do you get a different result? If so, please, post it.
Also, what do you use (tool / editor / programming language) to load the file format?
I'm thinking what the problem could be:
- I thought of Unicode's BOM but the initial bytes have ASCII codes like 0xFF or 0xFE so it doesn't seem likely
- mismatch of Little-Endian and Big-Endian loading of words longer than 8 bits (though, it would just shuffle the bytes - while you get bytes with completely different ASCII codes…)
- some issues with conversion from UTF-8/binary to a specific 8-bit character set - this seems most likely to me - curious to see how exactly you access the file in your approach.
Depending on what programming language you use, maybe you can take a look at ?page=support on some free libraries/tools in Pascal/C/PHP that have source code of loading the format.

After downloading the 1.1 version of the contra font, I can confirm the file I downloaded is still the same, and started with 0xD791D796, and then 0xD7, in contradiction to what should be.

Oh hey, I am back :D
I appreciate your reply a lot, admin!
I had expected that the version, according to the format, had to be 0x11 (11h). Any idea why the 5th byte at the contra font is D7h, instead of 11h?

"I downloaded the ?font=contra and ?font=4x5_64x30 fonts and looked at it in hexadecimal mode but couldn't find any occurences of 0xD7 or 0xA9."
I'm certain that the contra font has these bytes. At bytes 9 and A. How odd..

"The header is not 7 bytes long, it is 4 bytes long. As the ?page=format says, first four bytes is the constant 32-bit word representing the header..."
That is very weird. The contra file starts with 0xD791D796, unlike what it should be. What happened there?

"the 5th byte (or offset 4) is the font version, 6th byte (offset 5) is lineHeight and 7th byte (offset 6) is the sizeOver variable."
This here was very important for me to understand. Thanks a lot! :D

Could it be... the font I downloaded and the contra font you downloaded are different? I'll attempt to download the contra font again, and update you here.

I've finally written a one-click "delete the spam and ban its IP address" function into my admin. May become handy.
Also, some more (mild) milestones:
4800+ fonts, 2500+ monospaced, 2200+ proportional
1.2M total views
11K total tags, 4.1K general tags, 5.1K external links (avg 1.07 per font)
800+ artist attributions
at least 36 fonts per letter/digit

In past hours/days, has anyone had trouble - or any unusual issues - accessing this website? Please, tell. Thanks.

@Blawnode:
(I went ahead and published your comment (taken from the contact form) for you here so that I can answer it - hope you don't mind.)

The header is not 7 bytes long, it is 4 bytes long. As the ?page=format says, first four bytes is the constant 32-bit word representing the header, the 5th byte (or offset 4) is the font version, 6th byte (offset 5) is lineHeight and 7th byte (offset 6) is the sizeOver variable.
I downloaded the ?font=contra and ?font=4x5_64x30 fonts and looked at it in hexadecimal mode but couldn't find any occurences of 0xD7 or 0xA9.
As of the sizeOver variable (the byte at offset 6) in that font, its value is 0xF8 which (if interpreted as signed 8-bit integer) equals -7.
If I'm still missing something, please, explain further - I'd be glad to fix whatever seems to be wrong.
Thanks for your interest.

P.S. the spam word that got triggered was "ass" from "I assume" ;) - I've changed it now.

I was dissecting several .bmf's on the site, while looking at the format page, and noticed 2 odd discrepancies.
Why do many files (notably the CONTRA font file) start with a 7-byte header, different than the format page's header and other files (notably, the 4x5_64x30 font file)
And there's a couple of bytes (d7 a9 in the CONTRA file) which I assume are meant to be -7, representing size over and size inner - How does d7 a9 translate to -7?

@Blawnode: Sorry to hear that. The website faces an incursion of spammers so (in addition to reCAPTCHA) I had to filter messages with some most frequent spam words (the usual crap that's pushed).
If your message is legitimate and it still doesn't get through the filter, send it through ?page=contact
Thanks

Well uh... tried to send a long message and it was evaluated as a spam. What do I do haha

Converted few fonts from one website (NFG's Arcade Font Tool).
