The content of the string, that is, the human readable characters, didn't change, but it's now a valid UTF string. If you keep treating it as UTF, there's no problem with garbled characters.
As discussed at the very beginning though, not all encoding schemes can represent all characters. Unicode all the way Precisely because of that, there's virtually no excuse in this day and age not to be using Unicode all the way. Some specialized encodings may be more efficient than the Unicode encodings for certain languages.
But unless you're storing terabytes and terabytes of very specialized text and that's a lot of textthere's usually no reason to worry about it. Problems stemming from incompatible encoding schemes are much worse than a wasted gigabyte or two these days.
And this will become even truer as storage and bandwidth keeps growing larger and cheaper. If your system needs to work with other encodings, convert them to Unicode upon input and convert them back to other encodings on output as necessary.
Otherwise, be very aware of what encodings you're dealing with at which point and convert as necessary, if that's possible without losing any information.
Flukes I have this website talking to a database. My app handles everything as UTF-8 and stores it as such in the database and everything works fine, but when I look at my database admin interface my text is garbled.
An often-encountered situation is a database that's set to latin-1 and an app that works with UTF-8 or any other encoding. Pretty much any combination of 1s and 0s is valid in the single-byte latin-1 encoding scheme. After all, why not?
The database admin interface automatically figures out that the database is set to latin-1 though and interprets any text as latin-1, so all values look garbled only in the admin interface. That's a case of fool's luck where things happen to work when they actually aren't.
Any sort of operation on the text in the database may or may not work as intended, since the database is not interpreting the text correctly. In a worst case scenario, the database inadvertently destroys all text during some random operation two years after the system went into production because it was operating on text assuming the wrong encoding.
A parser would read this as follows: If you simply output this byte sequence, you're outputting UTF-8 text. No need to do anything else. The parser does not need to specifically support UTF-8, it just needs to take strings literally. Naive parsers can support Unicode this way without actually supporting Unicode.
Many modern languages are explicitly Unicode-aware though. Some portions of it are applicable to programming languages in general while others are PHP specific.
Nothing new will be revealed about encodings, but concepts described above will be rehashed in the light of practical application. PHP doesn't natively support Unicode.
Except it actually supports it quite well. These two functions seem to promise some sort of automagic conversion of text to UTF-8 which is "necessary" since "PHP doesn't support Unicode". If you've been following this article at all though, you should know by now that there's nothing special about UTF-8 and you cannot encode text to UTF-8 after the fact To clarify that second point: All text is already encoded in some encoding.
When you type it into the source code, it has some encoding. Specifically, whatever you saved it as in your text editor.
If you get it from a database, it's already in some encoding. If you read it from a file, it's already in some encoding. Text is either encoded in UTF-8 or it's not. If it's not encoded in UTF-8 but is supposed to contain "UTF-8 characters", 7 then you have a case of cognitive dissonance.
Text can't contain Unicode characters without being encoded in one of the Unicode encodings. That's all there is to it.
If you need to convert a string from any other encoding to any other encoding, look no further than iconv.
Rather, it seems to cause more encoding problems than it solves thanks to terrible naming and unknowing developers. Native-schmative So what does it mean for a language to natively support or not support Unicode?
It basically refers to whether the language assumes that one character equals one byte or not.Chapter 8: Strings. Strings in C are represented by arrays of characters. The end of the string is marked with a special character, the null character, which is simply the character with the value 0.(The null character has no relation except in name to the null leslutinsduphoenix.com the ASCII character set, the null character is .
How To: Read and Write ASCII and Binary Files in C++. (which include a string property) to files in ASCII and binary formats below. In this simple example we write and then read two objects to a file in ASCII mode, and then do the exact same thing in binary mode, which results in file sizes of: Bytes (ASCII) Vs.
33 Bytes (Binary). This is a C Program to find the sum of ASCII values of all characters in a given string. Problem Description This program takes a string as input and finds the .
C++ Program to Find ASCII Value of a Character A character variable holds ASCII value (an integer number between 0 and ) rather than that character itself in C programming. That value is known as ASCII value.
I'm trying to convert an ascii string to a binary string in C. I found this example Converting Ascii to binary in C but I rather not use a recursive function.
