Description Tisza Gergő 2012-06-02 21:03:11 UTC 
When a Lua script returns invalid UTF-8 (which happens a lot since there is no internal UTF-8 support in Lua so string functions are not binary safe), the page appears completely empty.

Example: http://scribunto.wmflabs.org/index.php/Module_talk:Utf8bug
Comment 1 Brion Vibber 2012-06-15 19:42:12 UTC 
Note that it's probably not Scribunto itself that's eating the text, but later parser processing that uses PCRE regular expressions in UTF-8 mode.

May need to stick in a UTF-8 validation step on the output from the Lua side though.
