I have created six swash character and I have created an otf file with my swash characters. I suddenly realized my file size have grown from 135 kb to 421 kb. I tested my file I have created one swash set but in my there is two swash set option.

It is unlikely to be a bug, and a file size of 421 kb is not too big. Many of my fonts are over 1 Mb for a single typeface.

Yes, but it is caused by six characters difference that more than doubled the file size.

Try Optimising the contours. Probably, there are way more points than are needed. Look at the hintline to see just how many there are in each swash glyph. If they are imported from images, there may be a lot.

They are not imported from images.

This is still an opened issue.

Do send the font project so we can look into this problem.

Thank you for sending the font project. I suspect the file is blown up due to the large kerning lookup.
If you leave it out, the file size becomes less than 100 KB.

I have an OTF file that contains 1182 glyhps and their kernings and this file size is 135 kb.
I am adding 6 more glyhps to this file and their kernings.
The new OTF file contains 1188 glyphs and their and this file is 421 kb.
Adding 6 more characters and their kernings more than doubled the new file size.
I know if I add new characters to my project file size will be bigger but just 6 glyhps and kernings shouldn't have to double.
It could be optimizing problem, perhaps?

I used Automatic kerning.
File without swash characters:
Kerning pair
17621/123922
File with swash characters:
Kerning pair
123922/123922

In my project file
Kerning pair
17711/123922
But in my OTF file
Kerning pair
123922/123922
It is weird.
