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

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.
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.
