    jsapi-util-strings: Ignore locale to compute the upper case of a char
    
    We used to compute camel-case name of properties using toupper(),
    however this is locale-dependent, while in this case we want to be sure
    that we're only using ASCII values.
    
    This is particularly problematic in Turkish (and maybe other locales)
    because there 'i'.toLocaleUpperCase() is 'İ', that is definitely not an
    ASCII char, causing problems to with our generated properties.
