If summary field text is in multi-byte encoding and we want to grep the first 150 chars of comment then a slightly strange char sometimes appears in history
Example: http://commons.wikimedia.org/w/index.php?title=Image:Venera-7_diagram.jpg&am... ============== (==Описание/Description== *ru:Межпланетная автоматическая станция «Венера-7»: 1 — панели солнечных батарей; 2 — датчик астроориентации; 3 — защитная �) ==============
I think, It's first byte of truncated two-byte char. So, we have to use "mb_substr" instead of "substr", is'nt it?
