I couldn't reproduce what I wrote above.  \r\n\r\n* Procedure\r\n  1. Change the weights of Noto Sans CJK {JP,KR,TC,SC} Thin to {240,200,170,130}\r\n  2. Change the weight of Noto Sans KR Thin 100\r\n  3. Install all 7 weights of Noto Sans JP (v 1.002), Noto Sans CJK {JP,KR,TC,SC} and Noto Sans KR with Thin's weight changes per #1 and #2\r\n  4. Install all 7 weights of 20140609 version of Noto Sans Simplified Chinese (weight is 100 for Thin)\r\n  5. Restart (not necessary, but just in case) Firefox, Chrome and Safari \r\n  6. View the attached HTML page in all three browsers; \r\n      - It has 8 columns for testing Noto Sans CJK/JP/KR?SC fonts with different OS2.usWeights for Thin (250, 240, 200, 170, 130, 100, 100). \r\n      - The last column is Apple SD Gothic Neo that comes in 9 weights\r\n      - It has 9 rows from font-weight in CSS ranging from 100 to 900. \r\n  7. Remove DemiLight instances of all Noto Sans* fonts.\r\n  8. Repeat 5 and 6\r\n\r\nResults:\r\n\r\n1. In step 6, all three browsers in all columns (except for the last which is \r\nApple SD Gothic Neo) use 'DemiLight' for font-weight={100,200,300}. \r\n\r\n2. In step 8 (with DemiLight removed), for font-weight={100,200,300) are \r\nrendered with 'Light'. \r\n\r\n3. The last column (Apple SD Gothic Neo) : Firefox on the one hand and \r\nChrome/Safari on the other hand behave differently. \r\n\r\na. Firefox : The last column (Apple SD Gothic Neo) is rendered in 9 distinct \r\nweight instances of Apple SD Gothic Neo\r\n\r\nb. Chrome and Safari : It appears that font-weight={100,200,300} are NOT \r\ndistinguishable. It appears that 'Apple SD Gothic Neo Light' is used for \r\nfont-weight={100,200,300}. The reason I'm not sure is Chrome's DOM Inspector \r\ndoes not give the full font name (including weight) in Computed section for \r\nthis font (it does give the full font names for Noto Sans fonts). \r\n\r\nGiven that all the browsers behave identically (except for Apple SD Gothic \r\nNeo), something in CoreText is at play here and we have to talk to Apple to \r\nfigure out what's going on. \r\n\r\nBTW, TextEdit can distinguish all 7 weights (it does not use numeric weight. I \r\ncan simply choose 'weight' in the menu).\r\n\r\nhttps://storage.googleapis.com/google-code-attachments/noto/issue-199/comment-3/thin_vs_light.html\r\n![](https://storage.googleapis.com/google-code-attachments/noto/issue-199/comment-3/Noto%20Sans%20CJK%20Weights%20-%20Chrome.png)\r\n![](https://storage.googleapis.com/google-code-attachments/noto/issue-199/comment-3/Noto%20Sans%20CJK%20Weights%20Firefox.png)\r\n![](https://storage.googleapis.com/google-code-attachments/noto/issue-199/comment-3/Noto%20Sans%20CJK%20Weights%20-%20Safari.png)\r\n...\r\nBlink (Chrome) bug : https://code.google.com/p/chromium/issues/detail?id=449310\r\nFirefox bug : https://bugzilla.mozilla.org/show_bug.cgi?id=1122693\r\n\r\nI'll file a bug against Webkit, too. \r\n...\r\n\r\nMoved from googlei18n/noto-fonts#199"}}
