[reportlab-users] Error using encoding="utf-8" to output RML to PDF

[Robert Sullivan]

Hi Robin,

In preparing the smallest possible example I discovered I don't get the
error when using Helvetica just with Gotham. So the entities are working
fine.

Here is the docinit snippet and we are using utf-16 encoding.

<docinit>
        {% if font == "Gotham" %}
            <registerTTFont faceName="{{ font }}" fileName="{{ asset_root
}}/{{ font }}-Book.ttf" />
            <registerTTFont faceName="{{ font }}-Bold" fileName="{{
asset_root }}/{{ font }}-Bold.ttf" />
            <registerTTFont faceName="{{ font }}-Italic" fileName="{{
asset_root }}/{{ font }}-BookItalic.ttf" />
            <registerTTFont faceName="{{ font }}-Black" fileName="{{
asset_root }}/{{ font }}-Black.ttf" />
            <registerFontFamily
                normal="Gotham"
                bold="Gotham-Bold"
                italic="Gotham-Italic"
                boldItalic="Gotham-Black" />
        {% endif %}
    </docinit>

Also using Python3.6 and Django 1.10.5, fyi, so the font is declared in the
context variable that gets passed to this template.

I'll look more into the Gotham font but any pointers would be appreciated.

Many thanks,

Robert
