Hello,
I occasionally have to deal with sequential numbers which is largely
contiguous, but contain gaps (e.g., Unicode code points).

$ { seq 1 10; seq 12 22; seq 26 34; } | uniq --sequential

Perhaps the following will suffice?
$ { seq 1 10; seq 12 22; seq 26 34; } | awk 'A&&(A+1)!=$1 {print} 1 {A=$1}'

Or, if you want to print the first value as well:
$ { seq 1 10; seq 12 22; seq 26 34; } | awk 'NR==1{print}
A&&(A+1)!=$1{print} 1{A=$1}'
