Nameless here for evermore

Have you ever tried to reproduce some text that contains a typo? That is, you try to type in some text that contains mistakes, for purposes of mocking whoever produced the original, mistake-laden rubbish?

You know how hard that is?

It’s almost impossible to reproduce some text that has spelling mistakes, or other typos. I, at least, tend to reproduce corrected text, text without typos. I intend to create text with typos or spelling mistakes. Instead, I create correctly spelled or otherwise correct text.

I don’t make typos in that case, and I don’t mistakenly misspell words, or otherwise transgress the boundaries of written English, but I don’t produce the text that I desire.

I am unaware of a name for this phenomenon in English.
