问题 Most of WinAPI calls have Unicode and ANSI function call For examble: function MessageBoxA(hWnd: HWND; lpText, lpCaption: LPCSTR; uType: UINT): Integer; stdcall;external user32; function MessageBoxW(hWnd: HWND; lpText, lpCaption: LPCWSTR; uType: UINT): Integer; stdcall; external user32; When should i use the ANSI function rather than calling the Unicode function ? 回答1: The simplest rule to follow is this. Only use the ANSI variants on systems that do not have the Unicode variant. That is on

The output from ScalaTest is colored to distinguish different states, but these end up as control codes and [34m Annoying garbage Is there any way to convince the Eclipse console to either respect or ignore these sequences, or to plug in a view that will? thegreendroid I am successfully using this plugin for Eclipse - ANSIConsole Jim Hurne The Target Management Terminal plugin for Eclipse understands ANSI escape characters, including color codes. I use it to run sbt with ScalaTest . The original Target Management Terminal plugin was designed to access remote systems. However, if you are

问题 I am looking for a way to convert a textfile with UTF8 encoding to ANSI encoding. How can i go around and achieve this in Visual Basic (VB6) and or vbscript? 回答1: If your files aren't truly enormous (e.g. even merely 40MB can be painfully slow) you can do this using the following code in VB6, VBA, or VBScript: Option Explicit Private Const adReadAll = -1 Private Const adSaveCreateOverWrite = 2 Private Const adTypeBinary = 1 Private Const adTypeText = 2 Private Const adWriteChar = 0 Private

问题 So we are migrating from Informix to Sql Server. And I have noticed that in Informix the queries are written in this manner: select [col1],[col2],[col3],[col4],[col5] from tableA, tableB where tableA.[col1] = table.[gustavs_custom_chrome_id] Whereas all the queries I write in SQL Server are written as: select [col1],[col2],[col3],[col4],[col5] from tableA inner join tableB on tableA.[col1] = table.[gustavs_custom_chrome_id] Now, my first thought was: that first query is bad. It probably

json_encode() non utf-8 strings?

问题 So I have an array of strings, and all of the strings are using the system default ANSI encoding and were pulled from a sql database. So there are 256 different possible character byte values (single byte encoding). Is there a way I can get json_encode() to work and display these characters instead of having to use utf8_encode() on all of my strings and ending up with stuff like \"\\u0082\"? Or is that the standard for json? 回答1: Is there a way I can get json_encode() to work and display

Unicode, UTF, ASCII, ANSI format differences

问题 What is the difference between the Unicode , UTF8 , UTF7 , UTF16 , UTF32 , ASCII , and ANSI encodings? In what way are these helpful for programmers? 回答1: Going down your list: "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself

What is ANSI format?

问题 What is ANSI encoding format? Is it a system default format? In what way does it differ from ASCII? 回答1: ANSI encoding is a slightly generic term used to refer to the standard code page on a system, usually Windows. It is more properly referred to as Windows-1252 on Western/U.S. systems. (It can represent certain other Windows code pages on other systems.) This is essentially an extension of the ASCII character set in that it includes all the ASCII characters with an additional 128 character
