Limitation[edit]

<nowiki>...</nowiki> and <nowiki /> tags and their content are internally replaced by a code, which may affect the result:

  • "{{sub|<nowiki/>*café noir|1|9}}" gives "'"`UNIQ--".
  • "{{sub|*café noir|1|9}}" gives "café noir".

Automatic newline[edit]

Due to the automatic newline feature/bug a newline is added before any "*", "#", ":", and ";" in the substring, except when the substring starts at the start of the string:

  • "{{sub|*test|1|4}}" gives "test".
