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').

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...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
