java - Unicode chars are converted to broken symbols when I use wkhtmltopdf -


I have HTML that contains some Unicode characters, and saved in "UTF-8" in the disk. I can use less to display it, all the characters are displayed well: 

  & lt; H1 & gt; One "?? Ĺ ?? Æ ?? Action? & Lt; / H1> & Lt; P & gt; Playç¨ ?? ź ?? Æ ?? ¥ æ ?? ¶å ?? Degree celsius ŧ§Ã ?? One ???? E. æ ± ?? I ¼ ?? É ?? ½æ ?? C ?? ± & LT; Code & gt; Action & lt; / Code & gt; Æ ?? ¥ å¤ ?? Ç ???? Ç ???? à ????   
 But when I use "wkhtmltopdf" to convert it to PDF, it shows broken letters:  
  broken unicode   
 My order is:  
  wkhtmltopdf - encoding utf-8 book. Html book.pdf   
 how to fix it? Finally I found the reason: I do not have Unicode fonts in my ubuntu server  
 
 
 P> I upload some TrueType fonts from my local Ubuntu server, everything works fine.   Freewind: / usr / share / fonts $ cd truetype / freewind @ freewind: / usr / share / fonts / truetype $ ls arphic ttf-dejavu ttf-lao free font ttf-devanagari -fonts ttf-liberation kochi ttf-hindi-fonts ttf-malayalam-fonts msttcorefonts ttf-ask-fonts-core ttf-oriya -fonts Open Office ttf-japanese-gothic.ttf ttf-punjabi-fonts sazanami ttf-japanese-mincho Ttf ttf-tamil-fonts takao ttf-kacst-one ttf-telugu-fonts Thai ttf-kannada-fonts unfonts ttf-bengali-   
 I just upload them all, this is Fixes the problem, although I do not know which font is the key.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
