Hello Nicholas,

On Sunday March 03 2024 10:33, you wrote to me:

When it comes to mapping the number of characters to the number of bytes, when
you look at the  UTF-8 encoding table, about two screens down here:

https://en.wikipedia.org/wiki/UTF-8

You can see that the length of the byte sequence can be determined just by
looking at the first byte. Look from bit 7 to the right. The number of '1'
bits equals the number of bytes in the character. All the follow up bytes
start with '10'. So to get the number of characters ignore the bytes starting
with '10' when counting the bytes.

Breaking a line should only occur /before/ a byte starting with '0' or '11'.

Knowing all that it should be doable to let Golded display properly.

Perhaps the best strategy is to have Golded alway use UTF-8 internally. Almost
everyone else does these days...

You'r welcome.


Cheers, Michiel
