I've trimmed sale_order_html.mako down to just the html, header and body tags with nothing except for BODY in in the body. I changed "## -- coding: utf-8 --" to "## -- coding: ascii --" in sale_order_html.mako, mako_header.html and mako_footer.html. I get the same error.

I changed "## -- coding: ascii --" to "## -- coding: utf-8 --" in sale_order_html.mako, mako_header.html and mako_footer.html. I get the same error.

sale_order_html.py has almost nothing in it so I've made no changes there.

Hi, ## -- coding: utf-8 -- in the head is just for the text in the document file, to be interperted correctly in variable you should use attribute .decode as I said : ${ (o.partner_id.title).decode('utf-8') or '' } .Did you try, this not works ??? Did you read documentation link ???? Bye

I pulled all the fields out of the .mako thinking that would accomplish the same thing (no fields, no .decode() needed.) I'd like for ANYTHING to work with mako2html, but; so far none of the examples, nor anything I program works. Even the most minimal case.

did you restart openerp server and update module ? What is log error message (the last 10 lines)

I did; "service openerp restart" has become my fastest typed phrase.

Too bad wraping <pre></pre> around that last comment doesn't get it to look correct. But, it's the same as the error in my OP (only poorly formatted, and the last bunch is truncated.)

I updated my original answer, good luck for the third error, perhaps try to verify with mako version 0.2.4. Bye

I reupdated my answer because line to add in th head of file mako was not displayed correctly. Bye

Thanks for all your time and effort @GEM. Does it work OK for you? If so would you tell me what versions you are using? I encounter errors left and right with Mako 0.7.1-1 so finally downgraded to 0.2.4. Where the "## -- coding: utf-8 --" resolves the encoding complaints. But other errors crop up.

'Fragment 'include file="mako_header.html"' is not a partial control statement at line: 4 char: 1' is fixed by removing mako_header and _footer.

FYI; I've opened another question here http://help.openerp.com/question/5087/how-do-you-make-appopenerpcom-sale_report_html-work-on-ubuntu-1210/.

line "## -- coding: utf-8 --" you wrote and used is bad, used this I give in my first answer (which I have updated) .... Bye

the line utf8 in file python is not the good syntax, you must use # -- coding: utf-8 -- , as I wrote in the original answer I have updated, restart openerp server and update the module. Bye

you must use line # -- coding: utf-8 -- not this you use and decribe in your answer and comments.Bye

One # or two ## gives the same result. Mako 0.2.4 is "active" and 0.7.1 is "non-active" via "yolk -l | grep Mako". So yes, I get past the encoding 'ascii' error, THANKS! Please update your answer to include the "pip install Mako==0.2.4" and I'll mark you as the answer.

FYI, the third error that I'm working on is "RML is not available at specified location or not enough data to print (2)! (None, None, None)" which I take it means "not enough data to print." I'd added the (2) as a marker in ../service/web_services.py exp_report() to identify which of 2 exactly the same error situations is arising.

updated. Hope this will work for the last error, try to remove line mako heder xor footer in mako line, restart and update. Bye

I removed the header and footer, same "not enough data" error. Trimmed .mako to "## -- encoding: utf-8 -- <html> <head> HEAD </head> <body> BODY </body> </html>" and still "no data."

But let's close this one out. I've started another one that is a little more general here http://help.openerp.com/question/5087/how-do-you-make-appopenerpcom-sale_report_html-work-on-ubuntu-1210/
