width, height = mask.size
mask = np.array(mask.resize((int(mask.size[0] / float(scale)), int(mask.size[1] / float(scale)))))
wordcloud = WordCloud(scale=scale, background_color='white', width=int(width/float(scale)), height=int(height/float(scale)), margin=2, font_path='msyh.ttc', mask=mask).generate(words)

[amueller]

looks like it can't open the font. Can you check if "D:\Usuários\dlsan\AppData\Local\Programs\Python\Python36-32\lib\site-packages\wordcloud\DroidSansMono.ttf" exists?
Can you also check what wordcloud.font_path is?

And just in case I'm wrong, can you please also see what happens if you remove the last line?

[hugovk]

This looks like a bug in Pillow on Windows with paths containing non-ASCII characters, from the accented á in Usuários.

A workaround is to copy the font to a path that contains only ASCII characters.

See python-pillow/Pillow#3145.

@hugovk good catch!
