Limitation

<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 "".
• "{{sub|*café noir|1|9}}" gives "".

Automatic newline

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 "".
