I have RTF strings stored in a blob field in my database table. Example 1: The following blob RTF string stores plain text - 'Gluten, oeufs, lait, fruits à coque':
{\rtf1\ansi\ansicpg1252\deff0{\fonttbl{\f0\fnil\fcharset0 Tahoma;}{\f1\fnil Tahoma;}}{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\lang4108\f0\fs16 Gluten, oeufs, lait, fruits \'e0 coque\f1\par}
Example 2:
{\rtf1\ansi\ansicpg1252\deff0\deflang4108{\fonttbl{\ \fnil\fcharset0 Tahoma;}{\f1\fnil Tahoma;}}{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\f0\fs16 Farine de froment, Gruy\'e8re AOP 28%, tomates, mayonnaise (huile de tournesol, oeufs, eau, vinaigre, moutarde, sucre, sel), cornichons (cornichons, vinaigre, sel, sucre, extrait d'\'e9pices, \'e9pices, antioxydant E224), eau, sel, levure, gluten, farine de malt d'orge, \'e9paississant E412, dextrose, \'e9mulsifiant E472e, agent de traitement de la farine E300\f1\par}
Stores : 'Farine de froment, Gruyère AOP 28%, tomates, mayonnaise (huile de tournesol, oeufs, eau, vinaigre, moutarde, sucre, sel), cornichons (cornichons, vinaigre, sel, sucre, extrait d'épices, épices, antioxydant E224), eau, sel, levure, gluten, farine de malt d'orge, épaississant E412, dextrose, émulsifiant E472e, agent de traitement de la farine E300'.
