To get the alphabet position you could just do c & 0x1F, this is case insensitive and just as readable as c - 96.

| Aug 3, 2015 at 11:50 | comment | added | deworde | I would really prefer to wrap "int numberOfChar = byteRepresentation - 96;" into its own function, getNumberFromChar(), just because it's a dirty little implementation detail which will break on edge cases such as other languages; being able to encapsulate that complexity has value. | |
| Aug 3, 2015 at 11:25 | comment | added | Ismael Miguel | @Jodrell You are correct. Excuse my mistake. Unicode also has UTF-16 and UTF-32. I mixed up the names. | |
| Aug 3, 2015 at 11:14 | comment | added | Jodrell | @IsmaelMiguel, annoying gripe but Unicode is a superset of ASCII, UTF-8 is a way of encoding Unicode. | |

@GeorgePhillipson, 'a' does indeed have a decimal value of 97. You can use this to avoid writing lots of code. Whilst this mapping is unlikely to change, it is still an implementation detail that others will need to know to understand your code. If you use this you should comment accordingly so other developers understand, or learn.

| Aug 3, 2015 at 11:04 | comment | added | Ismael Miguel | I see my comment passed the wrong idea. What I was trying to say is that the ASCII table you linked is only for the first 128 characters, but that there were made different extended versions with other characters. Something I didn't said before: utf-8 is a superset of ASCII, which means that this will work on a utf-8 string. | |

I think you need range checking or a special case for names that include say an apostrophe ('\'') like an Irish name. These could otherwise result in negative values.

Notice that the provided ASCII table only has the first 127 characters. There's the extended version that has some variants to include other glyphs(?) and accents and other weird characters (like ç).

| Aug 3, 2015 at 10:32 | comment | added | George Phillipson | Hi Jens I never knew that a = 97 etc, that is something new I have learned today. | |
