By default, the UnicodeString type will have an affinity for UTF-16, the same encoding used by Windows. In order to ease the recovery of these values, I've implemented also "normal" UDF like the following (I'm reporting only one, as they are practically the same): // CorrXY *****. Working with Allegro. The RightStr function takes 2 parameters. Shift JIS/932 is a multi byte encoding. There is not implicit conversion if you always use AnsiString as a variable type. These kind of functions do modify the string but since they are unaware of how Delphi manages strings, the length is not changed on return. Not requiring string conversions made our “AnsiString” types much simpler. UTF8String, which behavior changed between Delphi 2009 compiler and previous versions: our implementation is consistent and compatible with all versions of Delphi compiler - mimic Delphi 2009 UTF8String, without the charset conversion overhead - all. I do not want a TWideStringField here, because if I switch to other data access components they will assume a TStringField here - and a transition will be painfull. La definición del String como variable pasó de ser un AnsiString a un UnicodeString. Save this as uFrmPrincipal. I'd like to convert unicode strings to ANSI with this function : function convertU(ws : widestring) : string; begin result := string(ws); end;. Tôi đã lập.

W1058 Implicit string cast with potential data loss from 'string' to 'AnsiString'. @rudy: the only think that is true is that There was also no big difference between AnsiString and UnicodeString routines (except 2x more memory consumption). But note that, in C++Builder and unlike in Delphi, AnsiString and UnicodeString are classes, implemented in pure C++ and mimicking the behaviour of the Delphi built-in types. String: nas versões mais novas do Delphi (2007 em diante), equivale a UnicodeString. my app is a non-unicode app written in Delphi 7. Program the rest using string wherever you can, and ansistring in some I/O operations. But my newsserver has only a pascal newsgroup from borland :(Greets, Franz Does AnsiString have some method to convert to a C string? I'm sure it does.

I'd like to convert unicode strings to ANSI with this function : function convertU(ws : widestring) : string; begin result := string(ws); end;. If you still waste your time with TDBGrid, you’ll use these whenever you allow the user to multi-select. to honest think code above bit of mess, , feels trying guess change strings without knowing doing.

Utf8Decode/Utf8Encode are necessary if you want to use UTF-8 instead of the current code page for sintr storage. String declarations should only be changed to be AnsiString when dealing with storage buffers or other types of code that uses the string as a data buffer. Antigamente equivalia a AnsiString. On the other hand if your goal is saving binary data using a string-like memory allocation and representation, you can use the RawByteString in the same way you used AnsiString in past versions of Delphi. Since Allegro is written in C it expects ANSISTRING, so when compiling it returns a bunch of warnings because "implicit cast with potential data loss", where sometimes "potential" is "actual" and things don't. If you want to go mobile, those are not supported and you should use "string". If you want to send strings back and fort you should keep values in widestring variable. The __property class overloads all the operators necessary to make it look like an AnsiString, but it is still a different class, so you cannot pass it directly to the function. Since this was the main string type in Delphi 1 (16 bit Delphi), the only reason to use Short String is for backward compatibility. Delphi 7 already has WideString for. Note that the original string remains unmodified, as the const modifier indicates. This is particularly useful when passing strings to API functions which accept PChar's. String의 길이를 구할때.

As of Delphi 2009, it carries an explicit code-page indicator. Most of the VCL already defaults to ansistring for non-Unicode I/O, making things very backwards compatible. The "cast" to AnsiString converts the UnicodeString (16 bit) string to an AnsiString (8 bit). Long string (in Delphi's help AnsiString) represents a dynamically allocated string whose maximum length is limited only by available memory. The Wiert Corner – It’s too bad that you need workarounds to get ByteStrings working on mobile devices as there are APIs there (like shaders) that work best with them. I have a question about a code that i have to convert UTF8 strings to ANSI strings. They never made UCS4String into a native string type, even though the RTL is now flexible enough to support a native string with 4-byte characters.

Note for Delphi users: the string type is not supported (either as function parameters or as result values). String instead of a char*. Delphi WideString to AnsiString is different from Lazarus Utf8ToAnsi(). In C++Builder specifically (which uses the same RTL as Delphi), there is the AnsiStringT templated class that provides the same functionality as Delphi's AnsiString(N) type: template class RTL_DELPHIRETURN AnsiStringT : public AnsiStringBase Where CP is the desired codepage.
