The secure personalities are a-z, A-Z, 0-9, and also _ - (emphasize and also minus ), that besides the scheduled personalities that are made use of for the parameters.

Various other personalities will certainly offer troubles in some level. instance : if one parameter is an array ?param=array[content] ie will certainly show an url whit the square brackets url inscribed, which look hideous and also difficult to determine.

Yet the trouble is not just it's hideous, allows claim you have a jpg with a personality close to the more secure ones, sometimes the internet browser will certainly be incapable to download it obtaining a 404. This is a trouble of older internet browsers and also some mobile internet browsers.

Just how to examine this?

• place a number of images/js/css with the personalities you intend to examine in the names in a public web page with several site visitors
• Make the 404 web page send you a email every single time it get a hit

I have an inbox with 14000 e-mails confirming my factor.

The solutions below are excellent, yet there is another exemption I assume deserves stating - non-english personalities. Referencing this SF question here, personalities like ñ (as in Español ) are flawlessly reputable, IF they have actually been inscribed in your DNS appropriately.

You need to make use of Punycode within your DNS to get them to settle in modern-day internet browsers (the access for español is xn--espaol-zwa ) yet these are currently flawlessly secure to make use of in domain, as they're very easy for non-english-speakers to type too.
