Issue 58860

1) Write an unrecognized and uncapitalized word, in example, 'soteriology'
2) Add it to a personal dictionary
3) Write the same word but capitalized: 'Soteriology'
4) 'Spell checking' don't recognize it as a correct word.
This happend in english, frech, latin, spanish... and I guess, every language,
even at the begining of a paragraph.

I know that this is the way that 'Spell checking' should work for capitalized
words, like proper names, but not for uncapitalized. In example:
1) Write 'Condolezza'
2) Add it to a personal dictionary
3) Write 'condolezza'
4) 'Spell checking' don't and should not recognize it.
