There is nothing that software can't fix. Unfortunately, there is also nothing that software can't completely fuck up. That gap is called talent.

About Me

 

Excluding font outlines in Flex can shave off over 200kb!

Often when you need to embed a font you also need to include ‘bold’ and sometimes ‘italic’ styles. Sometimes you need more than one fontFamily. Flex by default will embed all glyphs of a fontFamily. Embedding every glyph if generally unnecessary. By restricting the character set (’unicode-range’) you can shave off between 50-100kb or more per font style (FontFamilies have varying amounts of glyphs and obviously varying complexities of outlines which effects how much you can save). Anyway by setting unicode-range for fonts we managed to shave 300kb off our application, I wasn’t expecting it to be so much so thought worth a blog ;)

@font-face {
src: url("assets/Arial.ttf");
fontFamily: Arial;
advancedAntiAliasing: true;
unicode-range: U+0030-U+0039, /* 0-9 */
U+0041-U+005A, /* Uppercase A-Z */
U+0061-U+007A, /* Lowercase a-z */
U+0021-U+002F, /* !"#$%&'()*+,-./ */
U+003A-U+0040, /* :;<=>?@ */
U+005B-U+0060, /* [\]^_ */
U+00A3-U+00A3, /* £ */
U+00A9-U+00A9, /* © */
U+00AE-U+00AE /* ® */
/* U+00BF-U+0259 FOREIGN CHRS */
}

if anyone knows of other ranges you think can be generally useful please let me know ;)
