This data is from database and the maximum length of a field is defined. I mean that every column has a maximum length and I want to use this maximum length as a separator. So if one "cell" in that column is shorter than the maximum, "cell" should be padded with white spaces or something like that. This seems to be hard to explain.
Your problem is the intermediate file. Why not get R to read directly from the database, using RODBC?

" This is an example" is 19 chars, including the leading space. You told R it was 18. " This is an " is only 12 characters. I would say you have two fixed width fields, and three varying fields, with no delimiters. If the middle one of the three always contains digits and the others don't, you can probably extract them using sub(), but you can't use any of the read.* functions to do this: your format is too strange.
