@traabot «Most normal matter in the universe consists of hydrogen (75%) and helium (25%), everything else - absolutely everything else except for a tiny bit of lithium - amounts to a mere fraction of a percent that has taken many, many stellar generations to produce.» (from https://blogs.scientificamerican.com/life-unbounded/httpblogsscientificamericancomlife-unbounded20110802the-molecules-that-made-the-universe/). Just tried to fact-check :)

@jwildeboer Interestingly, just found out that RFC3629 supersedes RFC2279, and one of the changes is the reduction of character range. Weird.

@jwildeboer Why "mb4" and not "mb6"? From RFC 3629 (or 'man utf-8'): «Another security issue occurs when encoding to UTF-8: the ISO/IEC 10646 description of UTF-8 allows encoding character numbers up to U+7FFFFFFF, yielding sequences of up to 6 bytes. There is therefore a risk of buffer overflow if the range of character numbers is not explicitly limited to U+10FFFF or if buffer sizing doesn't take into account the possibility of 5- and 6-byte sequences.»
