The multibyte calculation has been fixed, now we actually work out which characters take more than a byte. Diminishing returns has been modified, previously the multiplier would zero itself out due to floating point limitations

Subject: [PATCH] Fix PlayerEditBookEvent
|
|
|
|
- Updating book writing (not signing) mutated the original item, making
|
|
it impossible to properly cancel the event or modify the book meta
|
|
|
|
- When the event was cancelled, the client's book would keep the
|
|
cancelled writing
