 ## [Unreleased]
+### Added
+- Advanced setting to limit download filenames to ASCII characters. This is provided only as a workaround for OSes that do not properly handle standard Unicode filenames. This setting is generally not recommended and should only be used as a last resort ([@raxod502](https://github.com/radian-software)) ([#2305](https://github.com/mihonapp/mihon/pull/2305))

+- Download support for chapters with the same metadata. Now a hash based on chapter's url is appended to download filename to tell them apart, letting you download both. Existing downloaded chapters will continue to work normally ([@raxod502](https://github.com/radian-software)) ([#2305](https://github.com/mihonapp/mihon/pull/2305))
