Start with a few questions How often… do you need to write an application that deals with something else than ascii? do you need to write a multi-language application? do you write an application that has to be multi-language from its first version? have you heard that Unicode is used to represent non-ascii characters? have … Read more
To do this with cmd.exe, you’ll need to use the console properties dialog to switch to a Unicode TrueType font. Then use these commands: CHCP 65001 DIR > UTF8.TXT TYPE UTF8.TXT Commands: Switch console to UTF-8 (65001) Redirect output of DIR to UTF8.TXT Dump UTF-8 to console The characters will still need to be supported … Read more
I am sure there is no technical problem but maybe gmail and hotmail are not supporting that on purpose. This kind of websites have a wide audience and should be accessible from everywhere. Let’s imagine the user have a password in Japanese but he is on travel and go to a cyber cafe and there … Read more
Wow. On the one hand I’m thrilled to know that university courses are teaching to the reality that character encodings are hard work, but actually knowing the UTF-8 encoding rules sounds like expecting a lot. (Will it help students pass the Turkey test?) The clearest description I’ve seen so far for the rules to encode … Read more
There is no Unicode character that can be stored in one encoding but not another. This is simply because the valid Unicode characters have been restricted to what can be stored in UTF-16 (which has the smallest capacity of the three encodings). In other words, UTF-8 and and UTF-32 could be used to represent a … Read more
Unicode is a standard that defines numeric codes for glyphs used in written communication. Or, as they say it themselves: The standard for digital representation of the characters used in writing all of the world’s languages. Unicode provides a uniform means for storing, searching, and interchanging text in any language. It is used by all … Read more
From what I can gather in the documentation, they want you to get Character values from a String because it gives context. Is this Character encoded with UTF8, UTF16, or 21-bit code points (scalars)? If you look at how a Character is defined in the Swift framework, it is actually an enum value. This is … Read more
OK the question is “what are they for” and “Why are they in the middle of the Arabic Presentation Forms”. There was a need for a block of 32 non-characters “to make additional codes available to programmers to use for internal processing purposes” http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=IWS-Chapter04a#4d3110c8 It was required that it be in the Basic Multilingual Plane … Read more
It’s not a comparison with 0xc0, it’s a logical AND operation with 0xc0. The bit mask 0xc0 is 11 00 00 00 so what the AND is doing is extracting only the top two bits: ab cd ef gh AND 11 00 00 00 — — — — = ab 00 00 00 This is … Read more
