unicode

问题 I am trying to read a char from my ncurses terminal with mvin_wch() which returns a cchar_t, I know this is a struct with stuff like color information and a wchar_t. I can't seem to find any information about this cchar_t. I just wan't to know what it's members are named. I don't get why such an important part of the ncursesw library isn't documented anywhere. 回答1: If you have to know, read curses.h , but as noted, you are expected to manipulate cchar_t using the library calls, e.g., setcchar

问题 I am running into a display problem in Jupyter (both Classic and JupyterLab) for lists that include Arabic string elements and Latin Alphanumeric string elements. For example, if you run: en = '7X' print (en) ar = 'عربي' print (ar) print ([en, ar]) print ([ar, en]) Here is what you get: Obviously, where Arabic is the first element, Jupyter follows an RTL alignment displaying the ar element first on the right, but I don't know why the 'X' jumps from the alphanumeric element or how to fix that.

问题 In QML I have a TextArea. When I set the text property of this TextArea to "ÆØÅ" it shows "ÆØÅ" when the program runs. I also get text through some functions that I want to show in the same TextArea, but then "ÆØÅ" is shown as "???". The strings come from this C++ function: QString Tts::morseToChar(QString morse) { if(morse == ".-") return "A"; else if (morse == "-...") return "B"; ... ... else if (morse == ".-.-") return "Æ"; else if (morse == "---.") return "Ø"; else if (morse == ".--.-")

问题 I have a program that I created with two sections. The first one copies a text file with an integer in the middle of the file name in this format. file = "Filename" + "str(int)" + ".txt" the user can create as many copies of the file that they would like. The second part of the program is what I am having the problem with. There is an integer at the very bottom of the file that is to correspond with the integer in the file name. After the first part is done, I open each file one at a time in

问题 Background I'm working on a C++/MFC application and we've been converting it to display unicode characters to support foreign languages. For the most part this has been successful and unicode characters are displayed correctly. But I've encountered an issue where certain text on certain controls gets cut off. Example Here you can see a button that should display "ログアウト／終了" but gets cutoff and displays an unknown character in it's place. But if I pad the string with spaces it displays fine.

问题 How do I get my PostScript program to show G clef character from Bravura font? According to this SMuFL document the Unicode code point for a G (treble) clef in Bravura is U+E050 (see page 48 Clefs (U+E050–U+E07F)). The PostScript glyph name might be gClef (not sure). Here is my best attempt so far to get the unicode characters on page. I am using GhostScript 9.25 to produce a PDF. This is the output from GhostScript: GPL Ghostscript 9.25 (2018-09-13) Copyright (C) 2018 Artifex Software, Inc.

问题 I use Oracle 12c. I have below table in my DB. CREATE TABLE TEST_T (COL VARCHAR2(4000 CHAR)); I need insert multibyte characters in this table. The character is 3 byte character. I am able to insert only 1333 (upto 3999 bytes) characters in table. My expectation is to insert upto 1500 multibyte characters but I get ORA - 01461 . I don't want to change data type to CLOB or LONG. Is there any way to use VARCHAR2(4000 CHAR) to achieve this. Below is the code, SET SERVEROUTPUT ON DECLARE LV_VAR

问题 How can I search for a specific unicode character in an R package or a specific file (I am using the RStudio IDE). I am trying to submit a package to CRAN. All checks pass except for: W checking PDF version of manual (49.5s) LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! Package inputenc Error: Unicode character (U+008D) (inputenc) not set up for use with LaTeX. So when all Rd files are compiled to one pdf there seems to be a problematic

问题 Example in Python: >>> s = 'ı̇' >>> len(s) 2 >>> list(s) ['ı', '̇'] >>> print(", ".join(map(unicodedata.name, s))) LATIN SMALL LETTER DOTLESS I, COMBINING DOT ABOVE >>> normalized = unicodedata.normalize('NFC', s) >>> print(", ".join(map(unicodedata.name, normalized))) LATIN SMALL LETTER DOTLESS I, COMBINING DOT ABOVE As you can see, NFC normalization does not compose the dotless i + a dot to a normal i . Is there a rationale for this? Is this an oversight? Or is it not included because NFC
