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').

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne

c# - How can I find out if there are windows above a control? -

-
If I have Winforms controls, can it be possible to tell whether the window above it (from any application)? Actually, I have to know that some parts of my control are actually appearing on the screen. If you are happy to p / call, the EnumWindows function provides all top-level windows HWND on the screen is; This allows you to get a Non-Client Rectangle (GetWindowRect) to compare the limits of your form. This non-rectangular opaque areas (media player and fancy skins for choice), so you can be false positive for such a control window.

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
