Hi,
The incorrect currency symbol display in QWeb reports using web.html_container is often due to character encoding issues. Unlike web.basic_layout, web.html_container might not handle encoding automatically. The "Â" character indicates a UTF-8 encoding problem.
To fix this, start by adding <meta charset="UTF-8"/> to the <head> section of your QWeb template to explicitly set the encoding. Alternatively, use t-esc with formatLang to format the currency value according to the user's language and currency settings. Ensure the report is rendered with the correct language context and verify that your Odoo database uses UTF-8 encoding. If these solutions don't work, consider creating a custom QWeb helper function for currency formatting.
Eg:-
<t t-call="web.html_container">
<t t-set="data_report_margin_top" t-value="12"/>
<t t-set="data_report_header_spacing" t-value="9"/>
<t t-set="data_report_dpi" t-value="110"/>
<t t-call="web.internal_layout">
<t t-set="o" t-value="o.with_context({'lang': lang})"/>
<t t-set="company" t-value="o.company_id"/>
<t t-set="currency" t-value="company.currency_id"/>
<div class="header">
<!-- Header content -->
</div>
<div class="article" data-oe-model="your.model" data-oe-id="o.id">
<head>
<meta charset="UTF-8"/> <!-- Add this line -->
</head>
<!-- Your report content here -->
</div>
<div class="footer text-center">
<!-- Footer content -->
</div>
</t>
</t>
Hope it helps
