Tap and hold the file and choose "Open with Encoding". Then you can select the encoding with which you want to open the file.

If you change the encoding in the Document Properties popover, you select the encoding that is used when saving the file.

Can you give me an example? When did it work, when did it stop working?

I don't plan to do that.

Ok, now I could reproduce it. It happens when I delete the ".html" file and then create a new one from a template. There's no need to select the template twice to make it crash.

I'll fix it. Thanks for reporting this!

Did you have a chance to try it out yet? 

Does this happen every time? Unfortunately, I can't reproduce it on my device. 

Currently there isn't. Would you like to get a http:// link after you copy it on an FTP server? How is the app supposed to know which directory on the server corresponds to which public url?

Hello,

you can add your own themes to Textastic: http://www.textasticapp.com/v4/manual/lessons/How_can_I_add_my_own_syntax_definitions__themes_and_templates.html

I've found an Xcode theme at https://github.com/earcar/xcode-default.tmtheme

Sounds like a good idea. I'll consider it.
