Hello Oxwall team. Please look at that:

If user insert "tag" with the word that contain character " ' ", for example doll'z. It publish the post correctly, post is openable BUT.... After editing the post again, text area and tag area is broken.

Look at the screenshot - editing the blog post, after publishing. With the word doll'z as tag. Html editor gone, tag line doesnt work. (oxwall demo official)
