#3910 English Manual String Proc a in place of an

[Richard Gobeli]

There are two cases where "an" is used in front of Unicode. The "an" should only be used when the next sound is a vowel sound. The U in Unicode is a consonant sound so the "an" is incorrect it should be written as "a Unicode".

[David Billinghurst]

Agree. Fixed with commit [bb7ee1b07]
