IMHO caching framework tables should be converted to BLOB too. I 
experience the same bug there then I try to use pdf_generator2 
extension. It is generates pdf page and stores content in page's cache.

But if DB uses utf-8 then your data getting truncated after first symbol 
which is not in utf-8 (pdf_generator2 is not using utf-8 for encoding).

So even serializing in framework does not help here thus same fix 
needed. Really as I see serializing doesn't change encoding so it is not 
relevant to bug.
