Solution
there is a website link, open it and there is nothing special except a otf file. i will provide it in downloads.
for solve this challenge simply covert otf to ttx using ttx command in linux
command: ttx agilerut.otf
by doing this you get a file agilerut.ttx in same directory you are.

open file and you will find string as follow :
<LigatureSet glyph="a">
<Ligature components="m,a,t,e,u,r,s,c,t,f,braceleft,zero,k,underscore,b,u,t,underscore,one,underscore,d,o,n,t,underscore,l,i,k,e,underscore,t,h,e,underscore,j,b,m,o,n,zero,underscore,equal,equal,equal,braceright" glyph="lig.j.u.s.t.a.n.a.m.e.o.k.xxxxxxxxx.xxxx.x.xxxxxxxxxx.x.x.x.xxxxxxxxxx.xxx.xxxxxxxxxx.x.x.x.x.xxxxxxxxxx.x.x.x.x.xxxxxxxxxx.x.x.x.xxxxxxxxxx.x.x.x.x.x.xxxx.xxxxxxxxxx.xxxxx.xxxxx.xxxxx.xxxxxxxxxx"/>
</LigatureSet>
"m,a,t,e,u,r,s,c,t,f,braceleft,zero,k,underscore,b,u,t,underscore,one,underscore,d,o,n,t,underscore,l,i,k,e,underscore,t,h,e,underscore,j,b,m,o,n,zero,underscore,equal,equal,equal,braceright"
convert it to :
amateursctf{0k_but_1_dont_like_the_jbmon0_===}
and thats your flag
