Steps to reproduce

1, Declare responsive variables in script with Unicode variable names.' 2, Use in style via v-bind.

What is expected?

JS and CSS variable names both support Unicode variable names, so there is no problem compiling directly into Unicode CSS variable names?

    var(--472cff63-english);
    var(--472cff63-中文);
    var(--472cff63-にほんご);
    var(--472cff63-français);

What is actually happening?

Unicode JS variable names used in Style via v-bind() will be replaced with _ when compiled into CSS code. Then variable names with the same number of digits will be converted to the same.

    var(--472cff63-english);
    var(--472cff63-__);
    var(--472cff63-____);
    var(--472cff63-fran_ais);
