Several romanizations of Chinese dialects has some diacritics with less-known usage for typographic designers.

1. Pe̍h-ōe-jī use O͘ for pronounciation [ɔ], use a short vertical line for tone 8.
2. Foochow, Hinghwa and Kienning Romanizations (Bàng-uâ-cê, Báⁿ-uā-ci̍, Gṳ̄̄ing-nǎing Lô̤-mǎ-cī) use diaeresis below to dictinct some vowels.
3. Kienning Colloquial Romanized use macron twice on a letter for tone 4.
4. Min Nan syllabic consonant m and ng written in POJ and accented æ used in Hainan Romanized (Bǽh-oe-tu)

The results for me are:

1. The height of dot above right looks so tall in lowercase, this dot shouldn't be higher than macron in any lettercase.
2. Diaerasis below placed incorrect in some cases, and U with diaerasis below and other diacritic completely failed.
3. Both sans and serif were failed to implement tone 4 of Kienning Romanization
4. Æ is incrrect in DejaVu Sans.
