getDispositionHeaderValue() protected method

Fallback name: - Causes issues if contains non-ASCII characters with codes less than 32 or more than 126. - Causes issues if contains urlencoded characters (starting with %) or % character. Some browsers interpret filename="X" as urlencoded name, some don't. - Causes issues if contains path separator characters such as \ or /. - Since value is wrapped with ", it should be escaped as \". - Since input could contain non-ASCII characters, fallback is obtained by transliteration. UTF name: - Causes issues if contains path separator characters such as \ or /. - Should be urlencoded since headers are ASCII-only. - Could be omitted if it exactly matches fallback name.
