After update to version 4.1 - Imagegenerator UnicodeEncodeError: 'ascii' codec can't encode character

[dani.mac...@gmail.com]

Hello,

I finally updated yesterday to version 4.1. Unfortunately I get the well known UnicodeEncodeError in imagegenerator when processing spanish characters. I have tried all the tips I have found (reinstalling the font, checking locale, etc). 

It is weird, because some characters are being correctly generated (í) but some others don't (ó). And finally a character cannot not be generated at all and imagegenerator fails:

Can anybody give me a hint of where can be the problem?

Thanks!

Hello, Daniel.

What version of Python are you using?

What is 'user.translategenerator.ImageGeneratorTranslated'? It is not part of WeeWX. Most likely, it is creating image labels, which are not in unicode.

Thanks for your answer Tom.

Sorry, I tought ImageGeneratorTranslated was part of WeeWX. It is an skin from Nick Dajda (brewster76) https://github.com/brewster76/fuzzy-archer/blob/master/bin/user/translategenerator.py

Using Python 2.7.13.

Looking (briefly) through the code, it looks like Nick did not port it to Python 2. In particular, when he opens up the language configuration file, he did not specify an encoding, so the results will not be in Unicode.

Try changing line 87 from

language_dict = ConfigObj(language_config_path)

to

language_dict = ConfigObj(language_config_path, encoding='utf-8', default_encoding='utf-8')

No guarantees.

Worked like a charm.

Thank you very much Sir! 

I will create a pull request with the changes so other people can find easily the solution.

Regards,

Daniel
