Qt Mac (Re)move “Special Characters…” action in Edit menu

由 纵饮孤独 提交于 2019-12-22 10:17:15
问题 I am developing an application in Qt that rebuilds its menus very often. However, when we call clear(), and re-add the actions that we want in the menu, "Special Characters..." appears to remain in the menu. Is there any way to remove, or move this action to the bottom of the QMenu? Here is the code that rebuilds the menu: void MainWindow::initMenus(Tab* tab) { menuBar()->clear(); menuFile->clear(); menuEdit->clear(); menuSettings->clear(); menuHelp->clear(); ui_toolBar->clear(); menuBar()-

Search in solr with special characters

由 别等时光非礼了梦想. 提交于 2019-12-22 05:17:23

When i try to search in solr with "-" i receive a 400 error. I've tried to escape the character, so I tried something like "-" and "\-". With that changes solr doesn't response me with an error, but it returns 0 results. How can i search in the solr admin with that special character(something like "-" or "'"??? Regards UPDATE

Convert special characters to normal

问题 I need a way to convert special characters like this: Helloæ To normal characters. So this word would end up being Helloae . So far I have tried HttpUtility.Decode , or a method that would convert UTF8 to win1252, but nothing worked. Is there something simple and generic that would do this job? Thank you. EDIT I have tried implementing those two methods using posts here on OC. Here's the methods: public static string ConvertUTF8ToWin1252(string _source) { Encoding utf8 = new UTF8Encoding();

Convert ANSI (Windows 1252) to UTF8 in C#

由 ╄→гoц情女王★ 提交于 2019-12-21 18:37:28
问题 I've asked this before in a round-about manner before here on Stack Overflow, and want to get it right this time. How do I convert ANSI (Codepage 1252) to UTF-8, while preserving the special characters? (I am aware that UTF-8 supports a larger character set than ANSI, but it is okay if I can preserve all UTF-8 characters that are supported by ANSI and substitute the rest with a ? or something) Why I Want To Convert ANSI → UTF-8 I am basically writing a program that splits vCard files (VCF)

php to rtf, é becomes é

由 跟風遠走 提交于 2019-12-21 05:32:08
问题 Using this rtf class, I see my special characters getting converted, like é becomes \'C3\'A9 (that part is probably not the problem) Once I get it in rtf using php header, the resulting character (é) is seen as é . header("Content-type: application/rtf; charset=utf-8"); header("Content-Disposition: attachment; filename=$file_rtf"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private",false); Strange!

CLion - Carriage return? \r

由 六月ゝ 毕业季﹏ 提交于 2019-12-21 03:48:26
问题 I am using the CLion IDE and I am trying to do a carriage return. I am doing a print statement in C and have the following syntax: printf("\rHello World!"); which is inside a loop. The loop still prints every Hello World on its own line. There are no \n 's in my program.
