Instruction for editing font file 

I don't know how to append a character using ttf font file :)
My code: 
`lucksystem font edit -a -o "path to output file" -s ゴシック15 -S info15 -O "path to info output" -f "NotoSansMonoEX.ttf" -c a.txt`
It runs without any errors but I can't extract the output file as cz1 image.
When replacing output in font.pak file, CLANNAD_SS keeps crashing.
