[Blog] Blog url special character formatting

[liviopersonne]

Describe the bug
Some characters are badly formatted in the URLs of blog posts.
For example:

Title: Systèmes embarqués : Quand la technique s’adapte à l’usage
Url: .../systmes-embarqus-quand-la-technique-sadapte-lusage

We can see that "é" and "è" characters are deleted

Expected behavior
"é" and "è" characters should be formatted to "e"

Additional context
I already did this formatting in a google script:

var sanitizedName = name.toLowerCase().normalize("NFD").replace(/[\u0300-\u036f]/g, "")

Someone on stack overflow did this in C#:

string accentedStr;
byte[] tempBytes;
tempBytes = System.Text.Encoding.GetEncoding("ISO-8859-8").GetBytes(accentedStr);
string asciiStr = System.Text.Encoding.UTF8.GetString(tempBytes);

We should also handle special characters that might fail (e.g. /)

Yes ! In this example, the ":" is correctly reansformed into ""
