How to printf accented characters in ANSI C (like á é í ó ú)

阅读更多关于 How to printf accented characters in ANSI C (like á é í ó ú)

问题 I tried to printf with some accented characters such as á é í ó ú : printf("my name is Seán\n"); The text editor in the DEVC++ IDE displays them fine - i.e the source code looks fine. I guess I need some library other than stdio.h and maybe some variant of the normal printf . I'm using IDE Bloodshed DEVC running on Windows XP. 回答1: Windows console is generally considered badly broken regarding to character encodings. You can read about this problem here, for example. The problem is that

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? Bob77 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 Sub UTF8toANSI(ByVal UTF8FName, ByVal ANSIFName) Dim strText With CreateObject("ADODB.Stream") .Open

阅读更多关于 Colorama for Python, Not returning colored print lines on Windows

问题 I've installed colorama for python. I've imported the module as follows: import colorama from colorama import init init() from colorama import Fore, Back, Style print Fore.RED + "My Text is Red" and it returns the ANSI charaters.... esc[31mMy Text is Red This isn`t what I expected. Am I doing something wrong. Thanks. 回答1: I had this same issue on Windows 7 x64, I finally got the colors working without having to install anything new just by adding the argument convert=True to the init call.

decimal(s,p) or number(s,p)?

阅读更多关于 decimal(s,p) or number(s,p)?

问题 recently, while working on a db2 -> oracle migration project, we came across this situation. the developers were inadvertently creating new table structures using decimal(s,p) columns. I didn't remember Oracle supporting this, but then some digging showed that its a ANSI data type therefore supported by oracle. However, question for me remained - how is this data handled internally ? is there a cost of using ANSI types instead of Oracle's built in types ? Will there be an impact during the

How to do proper Unicode and ANSI output redirection on cmd.exe?

阅读更多关于 How to do proper Unicode and ANSI output redirection on cmd.exe?

问题 If you are doing automation on windows and you are redirecting the output of different commands (internal cmd.exe or external, you'll discover that your log files contains combined Unicode and ANSI output (meaning that they are invalid and will not load well in viewers/editors). Is it is possible to make cmd.exe work with UTF-8? This question is not about display, s about stdin/stdout/stderr redirection and Unicode. I am looking for a solution that would allow you to: redirect the output of

Which join syntax is better?

阅读更多关于 Which join syntax is better?

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 creates this huge record set then whittles to the actual record set using the Where clause. Therefore, it's

Colored text output in PowerShell console using ANSI / VT100 codes

阅读更多关于 Colored text output in PowerShell console using ANSI / VT100 codes

问题 I wrote a program which prints a string, which contains ANSI escape sequences to make the text colored. But it doesn't work as expected in the default Windows 10 console, as you can see in the screenshot. The program output appears with the escape sequences as printed characters. If I feed that string to PowerShell via a variable or piping, the output appears as intended (red text). How can I achieve that the program prints colored text without any workarounds? This is my program source

json_encode() non utf-8 strings?

阅读更多关于 json_encode() non utf-8 strings?

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? hakre 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 "

Can an ANSI C-compliant implementation include additional functions in its standard library?

阅读更多关于 Can an ANSI C-compliant implementation include additional functions in its standard library?

问题 Is an ANSI C-compliant implementation allowed to include additional types and functions in its standard library, beyond those enumerated by the standard? (An ideal answer would reference the relevant part of the ANSI standard.) I ask particularly because Mac OS 10.7 declares the getline function in stdio.h, even when compiling with gcc or clang using the -ansi flag. This breaks several older programs that define their own getline function. Is this a fault of Mac OS 10.7? (The man page for
