![]() ![]() I would use an extension for handling unicode to do this. When a blob is converted to text, it is assumed that it is a series of bytes that represents the UTF-8 encoding of the characters. The result are: UTF String #Chars #Bytes nonASCII Hex The resulting query string should be freed using sqlite3free (). char s 20 'some string' char query sqlite3mprintf ('insert into tbl5 values ('q') ', s) Otherwise you have a risk of SQL injection. Writing/retrieving your JSON properties by SQLite C API sqlite3bindtext (), sqlite3columntext () and sqlite3columnbytes () are also correct by specifying the length of the field or column. Don't use sprintf () but sqlite3mprintf (). The last row contains a Unicode string of 3 people having different Fitzpatrick modifiers linked by ZERO WIDTH JOINERs, making the string a familly displayed as a single glyph.Ĭonsider using this query: select case length(cast('a' as blob)) when 1 then 'UTF8' else 'UTF16' end UTF, s String, length(cast(s as char)) "#Chars", length(cast(s as blob)) "#Bytes", regexp('', s) nonASCII, hex(cast(s as blob)) Hex from t But this JSON property of the git image is an utf-8 string, and not a normal C or SQLite string (terminated by zero). Another more efficient way would be to use the regex() extension (mine uses an implementation of PCRE).Īs an example, create two DBs, one using UTF8 and the other UTF16.
