Can not merge 'NotoSans-Regular.ttf', 'SourceHanSansKR-Regular.ttf',

[ashakoshti1988]

I get error kind of this,but in my case format is ttf but still i am not able to merge those files.

fonttools/fonttools#743

Moyogo's response to that issue indicates multiple reasons why this is not expected to work. The fonts in question have more than 65K glyphs combined-- even with them both .ttf this still prevents a successful merge.

The unaddressed issue from the original bug is the fact that the failure it encounters is nondeterministic. Ideally, it would be the same failure each time. But a failure is expected.

Even if i subset the font from SourceHanSansKR-Regular.ttf and made it to lesser size using pyftsubset,it still fails with
pyftsubset SourceHanSansKR-Regular.ttf --unicodes=U+0000-007f --output-file=Nasa.ttf

It looks like the UPEM are different, and they need to be the same. The CJK font probably used 1000 and you might need to convert the font to use 2048 like usual ttf convention. I'm not sure what tools do that. You might bring this up with the fontTools folks, perhaps they have recommendations.
