python - Unicode handling in ReportLab -

-

I am trying to use ReportLab with Unicode characters, but this is not working. I tried to trace through the code until reaching the following line: 

  class TTFont: # ... def splitString (auto, text, doctor, encoding = 'UTF-8') : #. .. cur.append (n & amp; 0xFF) # & lt; - Here's the problem! (This code can be found in the repository of this code, in the file, in the query line 1059.)  
  Why is the value of  n  being tampered with ?!  
 
 In the row shown above, code is the code point of the character to be processed (e.g. 65 for 'A', 'A' 97, or 1588 for Arabic Sheen 'Shi').  cur  is a list that is filled with characters to be sent to the final output (AFIU). Before that line, everything (apparently) was working fine, but in this line, the value of  n  was increased, apparently subtracting it into extended ASCII category! 
 
 -I lose the value of ASCII, Unicode characters, I do not understand why this statement is useful, or why it is necessary! 
 
 So my question is, why the value of  n  is being tampered with here, and how should I proceed to fix this problem? 
 
  Edit:  
 In response to a comment regarding my code snippet, this is an example that causes this error: 
 
  my_doctemplate.build ([Paragraph (bullettext = none, encoding = 'UTF8', case-sensitive = 1, debug = 0, text = '\ xd8 \ xa3 \ xd8 \ xa8 \ xd8 \ xb1 \ xd8 \ xa7 \ Xd8 \ xac ', frags = [paratroag (fontname =' devisisdomo-bold obik ', text =' \ xd8 \ xa3 \ xd8 \ xa8 \ xd8 \ xb1 \ xd8 \ xa7 \ xd8 \ xac ', sub = 0, increase = 0, Greek = 0, Link = None, Ital C = 0, Strike = 0, Font Size = 12.0, Text Color = Color (0,0,0), Super = 0, Underlined = 0, Bold = 0)]))))  
 
 This is called  PDFTextObject._textOut ,  _formattext , which recognizes the font as  _dynamicFont , and accordingly calls  Font .splitStri ng , which is causing the error described above

What do you mean, "not working"? You have incorrectly reported the report source code what it is actually doing that the lower and upper byte of each 16-bit Unicode character is coded separately (the upper byte is written only when it changes, PDF seems to be customizable to make documents smaller). / P>

Please explain what is the problem is , not what you think is the underlying cause. It's likely that the characters you want to display are not present in the selected font only ('DejaVuSansMono-BoldOblique').

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
