One of the "novelties" of the NextGen Delphi compiler is immutable strings, which I find quite puzzling, for lack of a better word, given that Delphi already had reference-counted copy-on-write strings, and the NextGen compiler uses reference-counted strings. I always considered that Delphi's String type was ...Character 0 (#0/Ascii 0) is possible in an utf8 string. Its encoded the same as all other characters from 0 to 127 as a single byte in the utf8 string. Hence you would have problems with C string functions. best regards Kim Madsen TeamC4D www.components4developers.com "Olivier Pons" < [email protected] >wrote inDec 03, 2008 · writeln(f, UTF8String('['+Clef+']')); Close(f); end. Since UTF8String is an AnsiString, we can combine the code above with writeln of normal strings, which will be converted to AnsiStrings, as long as we keep away from high-ascii characters (since these would indicate the start of a UTF8 special character byte sequence). program UnicodeTextFile ... Sep 29, 2013 · With sample code attached, the problem was undeniable, though the immediate cause was soon identified: the Delphi wrapper’s failure to include a ‘don’t validate the UTF8’ flag (PCRE was traditionally a UTF-8 based library, so the Delphi wrapper was using UTF8String). Putting everyone’s work together, I posted a QC report. Soon after ...

As of Delphi 2009, it carries an explicit code-page indicator. UTF8String: 2GB: 16 bytes: A managed string in UTF-8 format, implemented as an AnsiString with a UTF-8 code page.

Delphi and Unicode Author: Embarcadero Technologies Subject:This page covers Unicode support in Lazarus programs (console or server, no GUI) and applications (GUI with LCL) using features of FPC 3.0+. The solution is cross-platform and uses UTF-8 encoding which is different from Delphi's UTF-16, but you can write code that is fully compatible with Delphi at source code level by remembering just a few rules.As I know that, when a field with Memo type stores Unicode data, it compressed data in UTF8 format. So that, in order to make query on this memo field, I have to create the query command in UTF8 format. But I don't know how to convert Unicode string (or WideString) to UTF8string. For example: Unicode ==>UTF8 string.For Unicode aware Delphi versions gnugettext.pas declares a function utf8decode which calls System. ... UTF8String): WideString; Do note, however, that these functions did not support 4-byte UTF-8 sequences (Unicode codepoints outside of the BMP), only 1-3 byte sequences (Unicode codepoints in the BMP). That was not fixed until Delphi 2009 ...The Length of a UTF8String is the number of encoded UTF codeunits, not the number of Unicode codepoints, or the number of visual graphemes the codepoints produce. - Remy Lebeau Nov 27, 2020 at 18:51 If U is a UTF8String, then Length (string (U)) is an often acceptable approximation to the actual number of "visible characters".For this OVH requires me to generate a signature, but their documentation does not provide much info on this other than: "$1$" + SHA1_HEX (AS+"+"+CK+"+"+METHOD+"+"+QUERY+"+"+BODY+"+"+TSTAMP) They do provide thin wrappers for other languages so I thought I could take a look at those and try to replicate it. I found the following for generating ... For-in works on strings, arrays, sets, and any other custom collection that implements the required iterators. Looping over an empty collection does nothing. The counter variable can not be modified inside the loop. The for-in loop construct is supported in Delphi from Delphi 2005 onwards. It was implemented in FPC 2.4.2.UTF-8 Conversion Routines. This topic lists all UTF-8 conversion routines. Converts a string encoded in Ansi to UTF-8. Converts a string encoded in ANSI to UTF-8 with a given code page. Converts a stream from ANSI to UTF-8 encoding. Detects the encoding of a given WideString. Detects if a string or a stream contains the UTF-8 byte-order mark.So the idea would be to make Utf8String a class and runtime optimize it so: Modern runtimes could create Utf8Strings that have the string data inlined in the body of the object instance, like System.String. We could provide alternative storage systems (current byte buffer, no-copy byte buffer, wrap an existing unmanaged blob). MemberGeneral. The package contains a wrapper (zmq.pas), and a higher level api (zmqapi.pas). It should work with ZMQ 2.2.x, and with 3.2.x. For version 2.2.x undefine zmq3, in zmq.inc. The dll's are not part of this repo, you can download the appropriate from the official distro, and rename it to libzmq.dll. This is a work in progress, please open ...Delphi supports the following predefined string types. String types Note: The default string type is UnicodeString. WideString is provided to be compatible with the COM BSTR type. You should generally use UnicodeString for non-COM applications. For most purposes UnicodeString is the preferred type. The type string is an alias for UnicodeString.Given the similarities in many cases, you might have to read an entire file to see if it is UTF-8 or ANSI encoded. When you open a Delphi unit in VSC, it keeps the formatting. If it is UTF-8 with BOM, it remains as such. But for a new file the default is UTF-8 with no BOM. And any file can be saved with that format, as you can see in the status ...Character 0 (#0/Ascii 0) is possible in an utf8 string. Its encoded the same as all other characters from 0 to 127 as a single byte in the utf8 string.

My client communicate with the server through web servises. I use a search by name servise with Get method to take a list of names depending on what letter, english or greek i'll type on the TEdit.Text. Delphi's NextGen compilers (Android, IOS) removed support for UTF8String, AnsiString and RawByteString. But if you look into System.pas you see that those types are still there but Embarcadero makes them inaccessible from outside of System.pas by prefixing them with an underscore that the compiler converts to the at-sign.Delphi 2010 fixes the bug that caused internal errors when linking in the PCRE OBJ files if TPerlRegEx is installed into a design time package.
