Hello,

Hi,
I find some fonts (for example https://www.devanagarifonts.net/fonts/DevLys-110-Wide-Normal)
But this is a true type with variable width. You have a small and fixed size font ?

Thx for your link for fonts alex. I already have a english font file which consists of const array of all characters from A-Z & a-z & 0-9. I had written a function such that it would read font array each character by character. Now I wanted hindi font file the same way as I had for english fonts so that i could use the same function to read it as an array. Can I get a const array of hindi fonts?

I can help you to make a const array if you make a single color bitmap of your font.

You can make a bitmap with the hindi character in order reducing any of this in a fixed size ?
Use a 'grid' of a size that you need for each character (example 10 x 12 or 8 x 11)
Also you can use a variable width but in this case please draw each character within a larger fix grid.

I Have done a hindi character in the software named 8x8 ROM pixel Font Editor. But I feel it is tedious to generate fonts for all characters by this procedure. Can i get any font generator tool or any hindi font const array containing all characters of size 8x11 or 10x12? Kindly help if available so.

I suggest you to install various fonts and writing on a black and white bitmap the ordered sequence separated by a space. (Similar to @ A B C D etc.)
Then you have to work on the bitmap in order to get all the characters with a constant width. If you can do so, attach the bitmap obtained in the next post and I will convert to a const array

Hi Alex,
I have made an attachment hindi font bitmap here. please send me the const array for this. Also when I was going through some documents yesterday online, I found that to generate hindi fonts, there is concept called UTF-16. Can u let me know the procedure also to move forward in this regard.

Please attach a bitmap where each character is in a grid with a fixed size !
