Self Learning - Xrumer

I was self learning with Xrumer and I noticed alot of the "text before field" had characters that xrumer couldn't make out.... ( I'm talking about random characters ) ... are these foreign languages or are some of these captchas?

But then captchas are images so I don't know if it would be random characters?

Can anyone shed light on this and possibly give some Xrumer self learning tips?

"foreign languages" most likely. If you visit the url where xrumer found this fields, you will see what it is.
