If I want to use special (non-English) characters like čžš, I get the following error:

This only happens when I put these characters in the html/php template files. The weewx.conf or skin.conf use these characters for parameter definition and correctly include them into tags when the html file is being generated.

I use standard weewx configuration, no modifications to engine.py etc. I checked and the utf-8 is defined in the html templates.

I appreciate suggestions how to make this work.

Hi,

In /etc/weewx/skins/neowx/skin.conf look for the line:

template = index.html.tmpl

under the [CheetahGenerator], it will probably be something like:

[CheetahGenerator]
....
[[ToDate]]
....
[[[xxxxxx]]]
template = index.html.tmpl

Is there an ‘encoding =‘ setting immediately below or above under the same [[[xxxxxx]]] stanza? If not try adding ‘encoding = utf8’, something like:

[CheetahGenerator]
....
[[ToDate]]
....
[[[xxxxxx]]]
template = index.html.tmpl
encoding = utf8

Save skin.conf and wait for the next report cycle to complete.

Thanks for your suggestion. I did have "encoding=utf8" defined, I rechecked once again.

I even moved it in the [[[day]]] section but it doesn't help, unfortunately.

My template file is actually index.php.tmpl. Does it make any difference?

My mistake, too used to index.html.tmpl. The correct setting is of course the name of the template file being used. One more thought, there could be an override coming from weewx.conf. Could you post the [StdReport] stanza from weewx.conf as well as skin.conf from the neowx skin.

Forgot to add, there should be no sensitive info in the [StdReport] stanza or skin.conf but do check before posting.

Check for an #encoding directive at the top of your template. For example, index.html.tmpl in the Standard template uses:

#errorCatcher Echo
##
## Specifying an encoding of UTF-8 is usually safe:
#encoding UTF-8
##
<!DOCTYPE HTML>
<html lang="en">
  <head>
    ## This choice should match the #encoding directive above
    <meta charset="UTF-8">

Thank you Thomas, your instruction fixes the issue! My template was missing the #encoding UTF-8. I entered this row above the <!DOCTYPE HTML>.

Many thanks.
