.. code::
local font = unicode_text.hexfont()
font.load_glyphs(io.lines("unifont.hex"))
font.load_glyphs(io.lines("unifont_upper.hex"))
local pixels = font.render_text("wð♥𐍈😀!🂐겫")
font:load_glyphs(io.lines("unifont.hex"))
font:load_glyphs(io.lines("unifont_upper.hex"))
local pixels = font:render_text("wð♥𐍈😀!🂐겫")
tga_encoder.image(pixels):save("unicode.tga")
The above code creates an 80×16 TGA file with white-on-black text.

font:load_glyphs(io.lines("unifont.hex"))

.. code::
local pixels = font.render_text("wð♥𐍈😀!🂐겫")
local pixels = font:render_text("wð♥𐍈😀!🂐겫")
tga_encoder.image(pixels):save("image.tga")
The above code writes an uncompressed 80×16 grayscale bitmap.
