Nowadays, some 35 years after the first Unicode ideas got drafted and 30+ years after the Unicode Consortium saw the light, UTF-8 is served my more than 95% of the web as shown in yesterday’s post UTF-8 web adoption is huge, closing 100%, but only soured up since around 2006..
I mentioned this:
It means that nowadays there is a very small chance you will see mangled characters (what Japanese call mojibake) when you’re surfing the web.
Below are some issues that happened not too long ago and still happen. I have reported them to all parties involved through web-care, but no response whatsoever, and this is bad: Unicode support beyond basic ASCII for the below systems are still broken even for relatively simple non-ASCII characters based in diacritics decorating a standard ASCII character.
Yes, I know the realm of encoding and code pages is a mess, especially when handling data in multiple layers of an application stack. That’s why I wrote this post in the first place, and have a whole encoding category of blog posts plus a Mojibake subset.

As promised mid last year in “fixing” ESXi “rsync error: error allocating core memory buffers (code 22) at util2.c(106) [sender=3.1.2]”, I would follow up on building a static rsync for ESXi one day.
So below a few links on how to do this, roughly in the order I found them (most via [Wayback] vmware rsync “3.1.2” static – Google Search):
Especially the last link has a great set of steps on how to build manually.

Note: notepad cannot correctly guess the encoding, see the “old new thing”: [Wayback] Some files come up strange in Notepad | The Old New Thing (talking about ANSI a.k.a. Windows-1252, UTF-16LE, UTF-16BE, UTF-8, UTF-7 somewith and some without BOM as Notepad does not understand all permutations)
David Cumps discovered that certain text files come up strange in Notepad. The reason is that Notepad has to edit files in a variety of encodings, and when its back against the wall, sometimes it’s forced to guess.

As a precursor to a post tomorrow showing that serving UTF8 does not mean organisations go without unicode problems, first some statistics.
The first Unicode ideas got drafted some 30 years ago in 1987. In 1991, more than 30 years ago, the Unicode Consortium saw the light. Nowadays more than 95% percent of the web-pages (close to 100% when you include plain ASCII) is served using the UTF-8 encoding.
It means that nowadays there is a very small chance you
will see mangled characters (what Japanese call mojibake) when you’re surfing the web.
Some nice graphs of unicode growth are at these locations are at these locations:
I think especially important are 2008 (when UTF-8 had outgrown all other individual encodings) and slightly after 2010, when UTF-8 alone covered more than 50% of the pages served. These exclude ASCII-only pages. Adding those would make the figures even larger.

[Wayback/Archive.is] ThinkPad T440p Touchpad Swap: Installing Correct Drivers – YouTube
One of the most common upgrades for any Haswell (xx40) series ThinkPad is to replace the awful button-less touchpad (sometimes referred to as the ClunkPad) with a T450 touchpad that has the proper buttons for TrackPoint users. However, getting the buttons to work properly on xx40 hardware can be tricky – particularly if you are running Windows 10. In this video you will see how to get drivers installed that will allow you to use the TrackPoint as if this were a T450! As always thanks for watching! Some of the guides I used for this video:
I have edited the link so they show forum post titles, added way-back links, and added some crucial information:
PLEASE NOTE:
BEFORE YOU PUT IN THE NEW TOUCHPAD, INSTALL SOME EXTRA BUMPERS/RUBBERS ALONG THE TOP OF THE LID, LEFT AND RIGHT OF THE WEBCAM.
THESE SHOULD BE ABOUT TWICE AS THICK/HIGH AS THE SMALL BUMPERS THAT ARE THERE ALREADY.
Recommended size ~WxH: ~6 x 2 mm or ~1/4 x 5/64 inch.
PLACE THEM IMMEDIATELY LEFT AND RIGHT OF THE EXISTING BUMPERS.
FAILURE TO DO SO WILL RESULT IN SCRATCH MARKS ON THE SCREEN FROM THE NEW BUTTONS!

Cool tip: [Archive.is] Minko Gechev on Twitter: “Tooling tip: When debugging, you can prevent stepping into framework/library code by using blackboxing. In @ChromeDevTools: ‣ Open the script you don’t want to enter ‣ Right click → Blackbox ‣ Pain free debugging ✨… “

I needed to search for IBAN numbers in documents and used this regular expression: [a-zA-Z]{2}[0-9]{2} ?[a-zA-Z0-9]{4} ?[0-9]{4} ?[0-9]{4} ?[0-9]{2} which supports the usual optional whitespace like in NL12 INGB 0345 6789 01.
It is based on a nice list with table of Notepad++ RegEx character classes supported at [Wayback] Searching | Notepad++ User Manual:
Character Classes
[set]⇒ This indicates a set of characters, for example,[abc]means any of the literal charactersa,borc. You can also use ranges by doing a hyphen between characters, for example[a-z]for any character fromatoz. You can use a collating sequence in character ranges, like in[[.ch.]-[.ll.]](these are collating sequence in Spanish).[^set]⇒ The complement of the characters in the set. For example,[^A-Za-z]means any character except an alphabetic character. Care should be taken with a complement list, as regular expressions are always multi-line, and hence[^ABC]*will match until the firstA,BorC(ora,borcif match case is off), including any newline characters. To confine the search to a single line, include the newline characters in the exception list, e.g.[^ABC\r\n].Please note that the complement of a character set is often many more characters than you expect:
(?-s)[^x]+will match 1 or more instances of any non-xcharacter, including newlines: the(?-s)search modifier turns off “dot matches newlines”, but the[^x]is not a dot., so that class is still allowed to match newlines.
[[:name:]]or[[:☒:]]⇒ The whole character class named name. For many, there is also a single-letter “short” class name, ☒. Please note: the[:name:]and[:☒:]must be inside a character class[...]to have their special meaning.
short full name description equivalent character class alnumletters and digits alphaletters hblankspacing which is not a line terminator [\t\x20\xA0]cntrlcontrol characters [\x00-\x1F\x7F\x81\x8D\x8F\x90\x9D]ddigitdigits graphgraphical character, so essentially any character except for control chars, \0x7F,\x80llowerlowercase letters printable characters [\s[:graph:]]punctpunctuation characters [!"#$%&'()*+,\-./:;<=>?@\[\\\]^_{sspacewhitespace (word or line separator) [\t\n\x0B\f\r\x20\x85\xA0\x{2028}\x{2029}]uupperuppercase letters unicodeany character with code point above 255 [\x{0100}-\x{FFFF}]wwordword characters [_\d\l\u]xdigithexadecimal digits [0-9A-Fa-f]Note that letters include any unicode letters (ASCII letters, accented letters, and letters from a variety of other writing systems); digits include ASCII numeric digits, and anything else in Unicode that’s classified as a digit (like superscript numbers ¹²³…).
Note that those character class names may be written in upper or lower case without changing the results. So
[[:alnum:]]is the same as[[:ALNUM:]]or the mixed-case[[:AlNuM:]].As stated earlier, the
[:name:]and[:☒:](note the single brackets) must be a part of a surrounding character class. However, you may combine them inside one character class, such as[_[:d:]x[:upper:]=], which is a character class that would match any digit, any uppercase, the lowercasex, and the literal_and=characters. These named classes won’t always appear with the double brackets, but they will always be inside of a character class.If the
[:name:]or[:☒:]are accidentally not contained inside a surrounding character class, they will lose their special meaning. For example,[:upper:]is the character class matching:,u,p,e, andr; whereas[[:upper:]]is similar to[A-Z](plus other unicode uppercase letters)[^[:name:]]or[^[:☒:]]⇒ The complement of character class named name or ☒ (matching anything not in that named class). This uses the same long names, short names, and rules as mentioned in the previous description.

Interesting project at [Wayback] Open Source Insights
Open Source Insights is an experimental project by Google.
Hopefully by now it is supporting more than just npm/golang/maven and by the time it sunsets, other projects take over.
The introduction was some 9 months ago: [Wayback] Introducing the Open Source Insights Project | Google Open Source Blog
