incompatible sizes of some icons (compared to fontawesome 4.7.0)

[sebhaase]

Comparing to fontawesome 4.7 I find e.g. that .fa-user ([&#xf007]) is narrower than the forkawesome (1.2.0) version. I could correct this by adding this style

.fa-user:before {
    content: "\f007";
    width: 23.7px;
    display: inline-block;
}

while the current version appears to be more like having an intrinsic width of

width: 20px;

For .fa-search-plus ([&#x\f00e]) I find a vertical off of being a two pixels higher than its "original" fontawesome counterpart. (font-size 30px, for font-size 52px the offset is 3px)

So, my questions would be:
Should / could this be fixed?
Did others notice similar discrepancies?
