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:

[NL] encoding blijft moeilijk, waarom toch? (dit keer in een brief van @xs4all)

Posted by jpluimers on 2015/02/24

Hoe moeilijk kan het toch zijn om je encoding goed te doen.

Deze keer uit een brief van xs4all:

encoding foutje...

encoding foutje…

Als je een trema in een brief zet, dan controleer je toch even dat die ook goed op de brief wordt afgedrukt?

Een “inverted question mark” (deze keer samen met een oe ligature) duidt vrijwel altijd op een encoding probleem.

Ook bij de bevestigings email ging het mis:

bij de beï¿œindiging van uw oude abonnement.

En jawel hoor: de encoding daar was geen UTF-8:

Content-Type: text/plain; charset=iso-8859-15
Content-Transfer-Encoding: 8bit

Even een korte inspectie om te zien of het een simpele UTF-8 naar ISO-8859-15 conversie fout betreft: nee.

karakter iso-8859-15
hex
utf-8
hex
Unicode
hex
Unicode
naam
Unicode block
ï 0xCF 0xC3 0xAF U+00EF LATIN SMALL LETTER I WITH DIAERESIS Latin-1 Supplement
¿ 0xBF 0xC2 0xBF U+00BF INVERTED QUESTION MARK Latin-1 Supplement
œ 0xBD 0xC5 0x93 U+0153 LATIN SMALL LIGATURE OE Latin Extended-A

Ik hoop dat een xs4all techneut hier voldoende aan heeft (:

Great Unicode presentation by

Posted by jpluimers on 2015/01/21

Stefan Heymann did a great presentation Character Sets and Unicode in Firebird at fbcon11. About 90% of it is not about Firebird, but about Unicode: a highly recommended presentation.

There is also a PDF version of the same presentation for easier reading/searching.

If you like Firebird, there is a whole bunch of Firebird related presentations from various authors shared by MindTheBird.

Delphi hinting directives: deprecated, experimental, library and platform

Posted by jpluimers on 2014/10/01

I’ve been experimenting with the Delphi hinting directives lately to make it easier to migrate some libraries to newer versions of Delphi and newer platforms.

Hinting directives (deprecated, experimental, library and platform) were – like the $MESSAGE directive – added to Delphi 6.

Up to Delphi 5 you didn’t have any means to declare code obsolete. You had to find clever ways around it.

Warnings for hinting directives

When referring to identifiers marked with a hinting directive, you can get various warning messages that depend on the kind of identifier: unit, or other symbol. Read the rest of this entry »

Recommended reads when dealing with Character Encodings in software

Posted by jpluimers on 2014/05/06

Apart from the mandatory Joel on Software article about Unicode and Character sets, these two articles are of great value too:

Fun to read from that blog is the Historical Technology  section including this article:

PS: The mandatory one is The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) – Joel on Software.
