Character showing up as diamond question mark only at end of line (Python>Text)

由 雨燕双飞 提交于 2019-12-23 17:10:15
问题 I'm working on a Python file that inputs a text file with Japanese characters (UTF-8) in it, takes some of the text, and writes it into a new UTF-8 text file. The problem I'm coming across is that for some reason whenever the Japanese character だ appears at the end of a line in the original input file, it comes out as a diamond question mark in the output file. Instances of だ before the end of a line read perfectly fine and the original input file has it reading perfectly fine even if it's at

Java image for control characters in JTextArea

由 梦想的初衷 提交于 2019-12-23 16:48:12
问题 I'm writing an application which consists of 2 panels. One JTextArea for entering text and another one for showing text. In these texts I have two special characters namely STX/ETX (0x02, 0x03 in ASCII). When I enter these characters they are shown as invisible or some other symbol. I would like to make them visible and copyable like in Notepad++: Could anyone point me to a solution how to achieve that with a (probably custom) JTextArea? Is it possible to overwrite Font images or something

How can I convert character references to UTF-8 strings in Ruby?

由 断了今生、忘了曾经 提交于 2019-12-23 13:09:17
问题 I have some content from feeds. In these feeds, UTF-8 characters are often encoded as character references, ie "å" is "å". To avoid double encoding these in my views (ie "å") I want to convert these back to normal UTF_8 characters. How can I do this in Ruby? I want: "å".convert_to_utf8 => "å" 回答1: The HTMLEntities gem is designed to do just this. require 'htmlentities' coder = HTMLEntities.new string = "élan" coder.decode(string) # => "élan" # or string.decode_entities # => "élan" 来源：

问题 I'm having an issue on the current project I'm working on. I have to get a query stored from a file into a variable, whose file only contains a query (It is generated by part of the program). For instance I use the following code: set /p query=<path\to\my\folder\fileContainingQuery.soql It works when the query isn't that long, but when its length is beyond 1024 characters, the query is truncated and since I gotta send it to another configuration file using the FART tool, that's quite not

Why does printf( “%c”, 1) return smiley face instead of coded char for 1

由 霸气de小男生 提交于 2019-12-23 09:34:03
问题 This is my code #include <stdio.h> int x,y; int main( void ) { for ( x = 0; x < 10; x++, printf( "\n" ) ) for ( y = 0; y < 10; y++ ) printf( "%c", 1 ); return 0; } It returns smiley faces. I searched everywhere for a code for smiley face or a code for 1 but I didn't manage to find any links whatsoever or any explanation why char value for 1 returns smiley face, when the ascii code for 1 is SOH. I researched answers for this question but I didn't find any answers that explain why this happens.

Numbers localization in desktop applications

由 我只是一个虾纸丫 提交于 2019-12-23 07:46:08
问题 In the number decimal category of Unicode, 460 decimal characters are defined (see this page for some examples). Unfortunately I could not find any character representing a digit regardless of its appearance. As a result, currently only Western Arabic numeral characters are understood by most software as digits. So you can not for example enter other number characters in the MS Excel. If Unicode had (at least) 10 code for digits 0 to 9 as pure numbers, not a glyph, we could use them in almost

问题 I want use character for the location (like in Google Maps) – location symbol. I want to ask if there is such a unicode character? 回答1: Pushpin appears to be the closest you will find. Here is one 📌. They are different variants. 回答2: Unicode has many codepoints that represent visual symbols instead of text characters, including various arrows, but none that look exactly like what you want. The closest I can find is U+25BC Down Black Pointer (▼) or maybe you would like U+27B4 Bow Arrow (➴).
