Question

we are having a database with utf8 as charset. now in one table we are having a value like 'HERBES-Herbe à poux' . now we have to convert it into 'HERBES-Herbe a poux' . i.e à-->a. We cannot have a replace function since the values are dynamic.

Please help us.

对你来说，什么是“特殊人物”？US7ASCII 字符集之外的任何内容？

您可能会使用该CONVERT功能

SELECT convert( <<your string>>, 'US7ASCII' )
  FROM table_name

假设存在特定字符到 US7ASCII 字符集的映射，该映射将用于替换该字符。如果没有定义映射，则该字符将被默认替换字符替换，即问号“？”。
