Here is a useful function that translates every latin accented character in a UTF-8 string to their non-accented equivalent. I found a lot of similar functions on the web, but only with a very small translation table.
How is the translation table created? I took a list of all Unicode characters and with a small script I decoded their description. Use when needed: Note that for some languages accents are very important and distinguish meaning of words. Also, for some languages, a non-accented counterpart may be a completely different character(s).
Alternative approach to remove accents is to use
iconv('UTF-8', 'ASCII//TRANSLIT', ...). Unfortunately,
that does not work very well for all accents.
