## Description
Fixes https://github.com/payloadcms/payload/issues/8107
This has been confusing for people from countries where characters
aren't latin, for example the Japanese file name:
フェニックス.png
Turns into:
ãã§ããã¯ã¹.png
Additionally, ensures type-safety for `DEFAULT_OPTIONS` and removes
unused `fileHandler` property from there, which isn't defined in the
`FetchAPIFileUploadOptions` type.
