Thanks; it worked.
(I moved the Shader::isAvailable() to just before the main loop)

Graphics / sf::Sprite white rectangle

Using the following code:

static void loadCourier(sf::Texture &courier, sf::Image &im)
{
    sf::Uint8 pxls[256 * 96 * 4];
    std::ifstream fl("Courier.pbm", std::ios_base::binary);
    if (!fl.good()) {
        std::runtime_error e("Could not load Courier.pbm");
        throw e;
    }
    fl.seekg(10, std::ios_base::beg);
    char c;
    unsigned int i = 0;
    while (fl.good()) {
        fl.get(c);
        pxls[i]=pxls[i+1]=pxls[i+2]=pxls[i+3]=((c&128)?255:0);
        pxls[i+4]=pxls[i+5]=pxls[i+6]=pxls[i+7]=((c&64)?255:0);
        pxls[i+8]=pxls[i+9]=pxls[i+10]=pxls[i+11]=((c&32)?255:0);
        pxls[i+12]=pxls[i+13]=pxls[i+14]=pxls[i+15]=((c&16)?255:0);
        pxls[i+16]=pxls[i+17]=pxls[i+18]=pxls[i+19]=((c&8)?255:0);
        pxls[i+20]=pxls[i+21]=pxls[i+22]=pxls[i+23]=((c&4)?255:0);
        pxls[i+24]=pxls[i+25]=pxls[i+26]=pxls[i+27]=((c&2)?255:0);
        pxls[i+28]=pxls[i+29]=pxls[i+30]=pxls[i+31]=((c&1)?255:0);
        i += 32;
    }
    im.create(256, 96, pxls);
    courier.loadFromImage(im);
    std::cout << "Loaded.\n";
}

Resources::Resources()
: courier(), textshader(), im()
{
    loadCourier(courier, im);
    // ...
}
// In .h file
class Resources
{
public:
    Resources();
    ~Resources();
    sf::Texture courier;
    sf::Shader textshader;
    sf::Image im;
    static Resources &get();
};
// ...
class CourierText : public sf::Drawable, public sf::Transformable
{
// ...
public:
    sf::Sprite s;
// ...
}
// In .cpp file
s.setTexture(Resources::get().courier, true);
states.blendMode = sf::BlendAlpha;
states.transform *= getTransform();
target.draw(s, states);
 

The sprite is a white rectangle.
