Though formatting mangled the registry key to add, the article is interesting: since 2003 (C# Builder 1), you can force the IDE to always save files as UTF8 which should alleviate a lot of encoding problems.
It beats me why this isn’t the default setting, but below is an example .reg file for Delphi 8 which should be easily transformed to more recent Delphi versions:
| Windows Registry Editor Version 5.00 | |
| [HKEY_CURRENT_USER\Software\Borland\BDS\2.0\Editor] | |
| "DefaultFileFilter"="Borland.FileFilter.UTF8ToUTF8" |
So basically (if formatting is kept), you browse to this key (replace Borland with the company for your specific Delphi version, and replace 2.0 by your IDE version):
HKEY_CURRENT_USER\Software\Borland\BDS\16.0\Editor
Then you add a new string value named DefaultFileFilter with value Borland.FileFilter.UTF8ToUTF8

The unmangled registry key (and more tips) was from [WayBack] BSC Polska: Hidden possibilities of Delphi 8.
Get the list of HKEY_CURRENT_USER paths for your Delphi version at Update to List-Delphi-Installed-Packages.ps1 shows HKCU/HKLM keys and doesn’t truncated fields any more.

If the Delphi compiler throws a Source: "W1025 Unsupported language feature: 'operator explicit'" at you, then it is likely that you forgot this, as per Uwe Raabe:
In the project options set “C/C++ Output file generation” to “Generate DCUs only” to get rid of the warning.

Note that the documentation still indicates that W1025 has been documented since at least Delphi 2007 ([WayBack] x1025: Unsupported language feature: ‘%s’) as a C++ header translation issue, and still is ([WayBack] X1025 Unsupported language feature: ‘%s’ (Delphi) – RAD Studio), despite other causes (like "W1025 Unsupported language feature: 'custom attribute'") fail if you have only installed the Delphi personality.

I thought I had scheduled a blog post about the great tool on [WayBack] SequoiaView Homepage, but didn’t. In the mean time, Paolo Buffa posted an overview with a really nice historic perspective:
Is amazing from how many years I’m using this program, and how many operating systems it managed to go thru almost unscathed, without modification.
Paolo Buffa
Source: [Archive.is] SequoiaView: a piece of history. – Data Center IT – Spiceworks
I still use it, despite it being quite old: 2002 era, written in Delphi 5. It’s beautiful in part because of its anciency, but also because it is so simple and intuitive that I still use it regularly.
The age also shows in the web page (which when writing it was still on-line): The SequiaView home page link above is actually a classic frame inside [WayBack] The SequoiaView Homepage. Back then, it was already starting to be considered obsolete to write HTML using frameset [WayBack] Framing (World Wide Web) – Wikipedia.
The SequoiaView [WayBack] Download Page even points to non-existing ftp-download URLs via counter CGI scripts:
None of them have been archived by the WayBack machine: https://web.archive.org/web//ftp://ftp.win.tue.nl/pub/home/sequoia//
To verify alternative downloads, just check these hashes:
hash command filename hash output $ md5Sequoia1.3Install.zipMD5 (Sequoia1.3Install.zip) = 28d356f2bafe258805794257c284a075$ md5Sequoia1_3XPInstall.exeMD5 (Sequoia1_3XPInstall.exe) = 142586a5cc7a0139bde8c13e5cc4d301$ shasumSequoia1.3Install.zip762ab30177a7f6a0d4f173fd2442ba7b61df4c2e Sequoia1.3Install.zip$ shasumSequoia1_3XPInstall.exec1db10a0f7d36adbc14b5a7a3f08fc35db1bee8b Sequoia1_3XPInstall.exe
I’ve a copy in my archive that I just use in a portable way: just copy over SequoiaView directory with these files in it:
Archives.colDEFAULT.COLImages.colLicense.txtMovies.colReleaseNotes.txtSequoia.cntSequoia.exeSEQUOIA.HLPSound.colYou can download this from gist.github.com/jpluimers/b0df9c2dba49010454ca6df406bc5f3d (ef94f1875377f4054e3a434f8942e1749f0af74a.zip).
A few things that could be fixed (if ever hopefully MagnaView open sources it: [WayBack] @jpluimers More @magnaview did you ever consider to open source the Delphi code for http://www.win.tue.nl/sequoiaview/ or give someone NDA access to fix some bugs?):

[WayBack] MMX Needs New Icons – Are You Willing To Help? – MMX:
I am pretty sure all of you already noticed: The current icons in MMX not only look a bit old, they also don’t look well on the Dark Theme. They are not alpha blended and are only available in 16 x 16 pixel size. This may become a problem when the IDE will support High DPI in the future.
Unfortunately the stock icons available in the market simply don’t fit the purpose of most of the individual icons needed, so custom designed icons seem to be mandatory.
…
I have been asked several times where people can donate to support the development of MMX. While I am still not planning to accept donations for the time I am going to invest in the development, donating for the icons is a good way to show your gratitude. If you are not a able or willing to donate – that’s OK. Anyway, please consider to spread the word about this.
Many thanks to all that already donated and those who are going to do so.
For those still looking for the link to the MoneyPool, here it is: https://www.paypal.com/pools/c/8e4alQxGzA

In [WayBack] Anyone here with an “F2092 Program or unit ‘?’ recursively uses itself” error in Tokyo? I have this error in Tokyo but the same project compiles ok in Berlin… – Luis Madaleno – Google+, I commented this:
Large circular reference cycles can trip the compiler into emitting this error (next to out-of-memory errors, access violations and internal errors and “unitX.pas F2063 Could not compile used unit ‘unitY.pas'”).
Solution that usually works: quit Delphi, delete .DCU files, start Delphi, build all, then compile. Cumbersome, time consuming, but since the error is intermittent and involves large code bases, it’s was hard to get it to R&D back in the days.

a method to detect when the menu was closed without a selection (i.e. none of the menuitem OnClick handlers fired). Add the unit below to your project and the form the popup menu is on will receive the custom messages defined in the unit when the menu appears or closes.
The solution by Peter Below in ExPopupList works from D5 on: [Archive.is] missing TPopupMenu features? – Google Groups.
Now you can hook the [WayBack] TControl.OnContextPopup Event for a [WayBack] TPopupMenu activation, and the custom Windows messages CM_MENUCLOSED, CM_ENTERMENULOOP and CM_EXITMENULOOP to monitor the state of the popup menu.
