I made some modifications/modernizations to the algorithm that determines how large a file is.
Previously, the site's engine simply looked at the length of the file containing the text and used that. Including html formatting and counted UTF8 characters by as many bytes that they occupied (up to 4).
Some text got wildly inflated, especially text with lots and lots of dialogue.
So I rebuilt the algorithm that checks the size to make it more accurate. So now the html formatting is stripped before counting and the characters are counted as characters, not as bytes. So for example an é used to count as 3 characters, now it counts as 1. Same for curly/smart quotes, they used to count as 3 but now as 1.
Most of you won't notice much difference. But for in-progress serials, things will be wonky for a bit. Now whenever a serial gets updated after the change, the first time it happens, its size might shrink and the larger the text, the bigger the absolute difference.
So yes, it might happen that you update a serial and watch your text size shrink the first time you do instead of increasing.
