I can't find where is right place to report this problem. I hope Chrome team will soon aware this problem and fixing it accordingly.
I don't know if I should clarify this as an error or not. I'll call this an issue, it's a serious issue actually.
This is an issue with Google Chrome Vietnamese version.
Well, Chrome Vietnamese use French as secondary preferred language for displaying web pages by default. This is not true. English is our secondary language here. At present, French isn't popular here anymore.
Appx. 90 percents of schools and universities in Vietnam teach English as a required subject.
Quoted from Wikipedia:
I hope Chrome team will spot this issue, evaluate the situation and change it accordingly in future release, to make Chrome experience more convenient for Vietnamese users.Various other languages are spoken by several minority groups in Vietnam. The most common of these are Tày, Mường, Khmer, Chinese, Nùng, and H'Mông. The French language, a legacy of colonial rule, is still spoken by some older Vietnamese as a second language, but is losing its popularity. Vietnam is also a full member of the Francophonie. Russian — and to a much lesser extent German, Czech, or Polish — is sometimes known among those whose families had ties with the Soviet bloc. In recent years, English is becoming more popular as a second language. English study is obligatory in most schools. Chinese and Japanese have also become more popular.
