TiddlyWiki will have problems displaying special characters unless it is set to use UTF-8.
If you are serving your TW from a web server you might need to add an {{{.htaccess}}} file with this in it:
{{{ AddCharset utf-8 .html }}}
If you edit your TW file with a text editor that doesn't handle UTF-8 then it may have saved as plain ascii and broken the special characters such as the ยป char after "options"
