Bad surprise of the day: SysUtils.TEncoding in XE2+ defaults to ANSI, while in XE it defaulted to UTF-8.

+Stefan Glienke Indeed, you’re right. The issue must be deeper somewhere. Don’t have time to investigate too much, I’m bypassing the RTL now (also have to work around the limitation that for utf-8 the TEncoding.GetString method returns an empty string if one character in the buffer isn’t utf-8)

I wouldn’t trust the RTL at all with loading non-ascii text, we’ve had it hang on invalid UTF-8 codes more than once.

Michael Kaplan Obituary – Berkowitz-Kumin-Bookatz | Cleveland Heights OH (and a whole bunch of info in zero width Unicode stuff)

Posted by jpluimers on 2018/01/02

I totally missed the passing of Michael Scott Kaplan some 2 years ago, so a belated R.I.P. is in place.

Obituary for Michael Kaplan, Michael Scott Kaplan, 45, passed away Wednesday, October 21, 2015, in Redmond, WA, after a brave battle with MS for 25 years. He was a lead software developer for Microsoft.

Michael was the leading source on i18n, L10N, Unicode, sorting, normalisation and other things having to do with languages, representations and writing.

Besides that he was a really nice guy of which I enjoyed his MSDN materials.

Other people enjoy that too, so I’m glad his writings have been archived: [first archive.is, second archive.is, WayBackSorting it All Out: Archives

Looking for more examples of Unicode/Ansi oddities in Delphi 2009+

Posted by jpluimers on 2017/09/25

At the end of April 2014, Roman Yankovsky started a nice [Wayback] discussion on Google+ trying to get upvotes for [Wayback] QualityCentral Report #:  124402: Compiler bug when comparing chars.

His report basically comes down to that when using Ansi character literals like #255, the compiler treats them as single-byte encoded characters in the current code page of your Windows context, translates them to Unicode, then processes them.

The QC report has been dismissed as “Test Case Error” (within 15 minutes of stating “need more info”) by one of the compiler engineers, directing to the [Wayback] UsingCharacterLiterals section of Delphi in a Unicode World Part III: Unicodifying Your Code where – heaven forbid – they suggest to replace #128 with the Euro-Sign literal.

I disagree, as the issue happens without any hint or warning whatsoever, and causes code that compiles fine in Delphi <= 2007 to fail in subtle ways on Delphi >= 2009.

The compiler should issue a hint or warning when you potentially can screw up. It doesn’t. Not here.

Quite a few knowledgeable Delphi people got involved in the discussion:

Some interesting encoding/Unicode/text articles on kunststube and links for test files of various encodings

Posted by jpluimers on 2016/08/17

After yesterdays post on Testing and static methods don’t go well together, I read around on Source (kunststube [WayBack]) a bit more and found these very nice articles on encoding,Unicode and text:

Related on those, some other nice readings:

20 resources on migrating to Unicode with Delphi | Software on a String

Posted by jpluimers on 2015/07/08

Great post by Marjan Venema when you need to migrate your old Delphi programs to the modern Delphi world: [Wayback] 20 resources on migrating to Unicode with Delphi | Software on a String.

I’m glad that some of the links overlap with what I posted and presented in the past at:

Well done Marjan!
