I think the maximum number of characters in user input ('gets') is 254.
The input that I need to have is a piece of BBCode and it is longer
than 254 characters. So my question is: is there any way to get longer
user input, and if not, is there a way to get around this?
Thanks in advance!

Why? And regardless, how hard would it be to test that assumption?

Is this by any chance on Windows? I think it was mentioned in another
recent thread that gets from a terminal has this limitation there.

Seriously.
longstring = "x"*10_000
puts "length of longstring: #{longstring.size}"
File.open('/tmp/longfile.txt','w') do |f|
f.puts longstring
end
File.open('/tmp/longfile.txt','r') do |f|
longstringin = f.gets.chomp
raise "strings are not the same!" unless longstring == longstringin
end
puts "same"
Output

It's not an assumption, I have tested it. After typing 254 (or so)
characters, you can't type anymore. Simple as that.

You might be reaching a limitation with the terminal you're using.
Ruby doesn't care:
$ echo {1..1000} | wc -c
3893
$ echo {1..1000} | ruby -e 'puts STDIN.gets' | wc -c
3893

As Adam already pointed out - no. It's apparently a limitation of your
terminal, not `gets`.
