unicode

问题 Most of the Arabic letters have multiple contextual forms for example the latter ب has general unicode 0628 . But if latter come in the beginning of word will take this form بـ‎ unicode FE91 . Middle = ـبـ‎ unicode FE92 . End of the word = ـب‎‎ unicode FE90 . I'm trying to get the char code but i always get the general unicode. procedure TfMain.btn2Click(Sender: TObject); const Str = 'يبداء'; Ch = 'ب'; begin ShowMessage(IntToHex(Ord(Ch), 4)); // return 0628 - Correct ShowMessage(IntToHex(Ord

问题 In our website, some Mac users have troubles when they copy-paste text from PDF files into a TextArea (handled by TinyMCE). All accentuated char are corrupted, and became for example e? for a é , i? for a î , etc. I cannot reproduce this problem with a Windows computer. When I wrote the content of the TextArea on a file (before inserting it in the database), I just discovered that the initial é is visually different that a traditionnal é (on Vim, see below). Indeed : // the corrupted é -

问题 What is the difference between utf8mb4_0900_ai_ci and utf8_unicode_ci database text coding in mysql (especially in terms of performance) ? 回答1: The encoding is the same. That is, the bytes look the same. The character set is different. utf8mb4 has more characters. The collation (how comparisions are done) is different. The perfomance is different, but it rarely matters. utf8_unicode_ci implies the CHARACTER SET utf8 , which includes only the 1-, 2-, and 3-byte UTF-8 characters. Hence it

问题 I have got the following problem: When I plot anything with ggplot2 like this # Libraries library(ggplot2) # create data xValue <- 1:10 yValue <- cumsum(rnorm(10)) data <- data.frame(xValue,yValue) # Plot ggplot(data, aes(x=xValue, y=yValue)) + geom_line() The resulting graph looks like this where the text is shown in weir unicode blocks: ggplot2 graph with text issue These unicode blocks look like boxes with four numbers starting with two 0s like: # Example block ---- |00| |2C| ---- I

问题 I'm working on parsing files with Shift-JIS encoded strings within the binary data. My current code is this: public static string DecodeShiftJISString(this byte[] data, int index, int length) { byte[] utf8Bytes = Encoding.Convert(Encoding.GetEncoding(932), Encoding.UTF8, data); return Encoding.UTF8.GetString(utf8Bytes); } It works fine and I am able to get usable strings from this method, although when I display strings with Latin characters into my WinForms application, I see that the

问题 I'm quite familiar with Beautiful Soup in Python, I have always used to scrape live site. Now I'm scraping a local HTML file (link, in case you want to test the code), the only problem is that accented characters are not represented in the correct way (this never happened to me when scraping live sites). This is a simplified version of the code import requests, urllib.request, time, unicodedata, csv from bs4 import BeautifulSoup soup = BeautifulSoup(open('AH.html'), "html.parser") tables =
