TOC names with wiki section syntax not imported into odt format

[ghost]

For Telugu WIkisource, I am using {{C| section name}} with section heading wiki syntax like two or three is equal to signs. When importing to odt, these are appearing as {{{1}}}

Sample page: http://te.wikisource.org/wiki/%E0%B0%B5%E0%B0%BE%E0%B0%A1%E0%B1%81%E0%B0%95%E0%B0%B0%E0%B0%BF:Arjunaraoc/%E0%B0%AA%E0%B1%81%E0%B0%B8%E0%B1%8D%E0%B0%A4%E0%B0%95%E0%B0%BE%E0%B0%B2%E0%B1%81/%E0%B0%86%E0%B0%82%E0%B0%A7%E0%B1%8D%E0%B0%B0%E0%B1%81%E0%B0%B2%E0%B0%9A%E0%B0%B0%E0%B0%BF%E0%B0%A4%E0%B1%8D%E0%B0%B0%E0%B0%AE%E0%B1%81-%E0%B0%AA%E0%B1%8D%E0%B0%B0%E0%B0%A5%E0%B0%AE%E0%B0%AD%E0%B0%BE%E0%B0%97%E0%B0%AE%E0%B1%81
