![]() ![]() Moreover, I can tell that Visual Studio 2008 cpp/h files and behaviour is ANSI-like, so we may say that ANSI is still used today by a certain amount of people. Then you may say no also, I don’t want to get a “balls breaking” point for a such a request :lol: It’s just everything related to coding a multi-target JUCE application with french strings and Windows is enough boring as it is… (I have just thrown all my JUCE_T("") for the UTF8 representation of strings thanks to the IntroJucer utility :mrgreen: ) Or maybe just adding something about that in the JUCE documentation. So, what I propose is the just the following : adding a function in the String class which returns a char, so anybody who manages ANSI coded data would be able to access to characters coded between -128 and -1 or 128 and 255, without using something I judge personnally not “JUCE spirit-compatible” like a static cast. I have to confess I am not at all familiar with the use of the cast instruction. I have been able to succeed because I have seen this thread. However, before I have found the solution to do the conversion from ANSI to Unicode / UTF8, I was looking for a “simple” solution in the JUCE classes, I mean a function of the String class I just have to call to get what I expect, and I did not find it. I understand that what I have tried to do is not used by everybody here And I don’t think JUCE is the cause of Visual Studio strange behaviour :mrgreen: Well, is it that wrong to think that one of the String function should return the content of the data with 8 bits instead of 7 ? I don’t think I am the only one who uses Strings for languages other than English with special characters, like French or Spanish ?Īnd my bad about the length of the original ASCII table The toCharArray() function is a useful tool for converting a String object to a char array in the Arduino programming environment. ![]() ![]() And when the String is displayed correctly in JUCE, what is displayed by Visual Studio is wrong :lol: Well, some kind of… If the String contains “special french characters”, they are correctly displayed when they are coded as ANSI, and treated wrongly by JUCE (which considers them as UTF8). I would have liked a function which returns a char pointer, to get values between 0 and 255 or -128 / 127, whatever…Īnd one of the reasons why it annoyed me is because Visual Studio 2008 has the capability to show the content of the String classes in debug mode. However, if S is going to be modified, you should copy the string, as writing to R.c. ![]() So I had to use a cast to get what I needed. First of all, you would have to allocate memory: char S new char R.length () + 1 then you can use strcpy with S and R.cstr (): std::strcpy (S,R.cstr ()) You can also use R.cstr () if the string doesn't get changed or the c string is only used once. My problem was that the standard JUCE functions of the String class are unable to give something as simple as the ASCII value of the extended characters, because of the use of the juce_wchar : they give only values between 0 and 127. You do know that you can’t get a value beyond 127 with a signed char on a platform where sizeof(char) = 1 byte, right? So there’s no reason at all to bother caching the pointer that it returns.įirst, I have found a workaround, so I have code which allows me to do the conversion successfully I deliberately avoided giving the String class an operator const char*() because I think it’s best to always see “toUTF8()” in code that uses it, so that any reader will immediately be aware that a raw pointer is being taken, and that the encoding is UTF-8.Īnd it’s worth noting that toUTF8() is completely free - it just returns a pointer to the underlying string, so compilers will optimise it down to nothing. And it’s far less efficient than taking a copy of the String, which would simply involve a ref-count, not a malloc/copy.Īnd I wouldn’t wrap it in an object with an implicit cast to const char*, because this isn’t an operation that should be hidden from view. I wouldn’t use strcpy, because it’s just so 1990s. By Using charAt () Method The charAt () method is a part of String class. charAt () method toCharArray () method 1. The following are the methods that will be used in this topic to convert string to char. But the best way to keep a copy of that char* is to just keep the String object, and then call toUTF8() on it whenever you need the raw pointer. How to convert Java String to char In Java, a String can be converted into a char by using built-in methods of String class and own custom code.
