TLDR "=\r\n" was converted to "=\n"

Author seems to think Unix uses a character called "NL" instead of "LF"...

Unicode labels U+000A as all of "LINE FEED (LF)", "new line (NL)" and "end of line (EOL)". I'm guessing different names were imported from slightly different character sets, although I understand the all-uppercase name to be the main/official one.

Oh okay... for a technical article, referrring to 0A with two different names within the same sentence of each other is not confusing at all... /S

Geezus...

NL, or New Line, is a character in some character sets, like old mainframe computers. No need to be snarky just because he mistyped or uses a different name for something.

I am more surprised by the description of “rock döts”. A Norwegian certainly knows that ASCII is not enough for all our alphabetical needs.

The writer presumably knows that umlauts and other non-ascii characters are functional in many languages. "rock döts" is poking fun at the trend in a certain tranche of anglophone rock/metal to use them in a purely aesthetic way in band names etc.

No, the article is quite explicit that that isn't what happened.
