How to properly encode UTF-8 txt files for R topic model

阅读更多关于 How to properly encode UTF-8 txt files for R topic model

问题 Similar issues have been discussed on this forum (e.g. here and here), but I have not found the one that solves my problem, so I apologize for a seemingly similar question. I have a set of .txt files with UTF-8 encoding (see the screenshot). I am trying to run a topic model in R using tm package. However, despite using encoding = "UTF-8" when creating the corpus, I get obvious problems with encoding. For instance, I get < U+FB01 >scal instead of fiscal , in< U+FB02>uenc instead of influence ,

Perl + Curses: Expecting a UTF-8 encoded multibyte character from getchar(), but not getting any

阅读更多关于 Perl + Curses: Expecting a UTF-8 encoded multibyte character from getchar(), but not getting any

问题 I am trying out Bryan Henderson's Perl interface to the ncurses library: Curses For a simple exercise, I try to obtain single characters typed on-screen. This is directly based off the NCURSES Programming HOWTO, with adaptations. When I call the Perl library's getchar() , I expect to receive a character, possibly multibyte (It's a bit more complicated as explained in this part of the library manpage because one has to handle the special cases of function keys and no input, but that's just the

Deprecated header <codecvt> replacement

阅读更多关于 Deprecated header replacement

问题 A bit of foreground: my task required converting UTF-8 XML file to UTF-16 (with proper header, of course). And so I searched about usual ways of converting UTF-8 to UTF-16, and found out that one should use templates from <codecvt> . But now when it is deprecated, I wonder what is the new common way of doing the same task? (Don't mind using Boost at all, but other than that I prefer to stay as close to standard library as possible.) 回答1: std::codecvt template from <locale> itself isn't

Problems: I am not sure what ranges of hex represent Chinese. The test may include Korean and Japanese. ("CJK") In MySQL 4

How to “remove diacritics” from UTF8 characters in PHP?

阅读更多关于 How to “remove diacritics” from UTF8 characters in PHP?

问题 I need to replicate the behavior of MySQL utf8_general_ci collation in PHP. Strictly speaking I need to detect what whould be considered different and what would be considered the same. The case independent part is easy. The problem is utf_general_ci considers characters with diacritics and characters without diacritics to be equal: e = è = é etc.. To replicate that comparison, I'd need to have a way to replace è -> e, é -> e. The method that comes to my mind is: echo iconv("utf-8", "ascii/
