When i18n_field module is enabled, we are calling it's function i18n_string_translate() to build the term levels options list. By default this leads to check_plain() being called on the term level strings. Since this module handles sanitization on it's own when rendering we are calling check_plain() multiple times on the same string. This can result in broken output when using special chars in the term level names.
We should disable sanitization by passing a parameter when calling the i18n_string_translate() function.
