There is a small problem for some letters with two macrons. For example, when you compare Ū̄ and Ṳ̄̄ in FreeSerif Bold Italic, you will see different alignment, I feel the next one is set an good example to other letters with two macrons.

I don't know what MediaWiki people would know about it.
The kerning happens on the local system (your computer) not elsewhere.

Well, I don't know why they are being pre-composed as bug #44480 mentioned, it's batter asking MediaWiki developers for help.

Yes, I put anchors on more pre-composed characters.

I wish I knew why they are being pre-composed.

Hi Steve,

I found a problem again when I open this page, the diaeresis below looks positioned incorrect with Ǎ and Ǒ.

Thanks. I have accessed Minbei and Puxian Min Wikipedia test wiki from here, they are all used ṳ for romanized texts, then I found Minbei Wikipedia have a link to provide an input method for Jian'ou Romanization, which can input U+1E73 directly.

I see. I had somehow missed the point that positioning accents over the u with dieresis below was the problem.

Note that you are using the letter U+1E73 (u with dieresis below) dierectly. I would expect that usually people would use the combination:


But anyway. It's fixed now.

Hi Steve,

I have tested again as attachments mentioned, found i̍ (only in italic types), ṳ̀, ṳ́, ṳ̂, ṳ̄, ṳ̆, ṳ̌, ṳ̍ still incorrect.

Hi Hsing-yen,

Most of these positioning issues should be resolved now.

Regarding the double-macron, I still recommend that you consider a proposal to Unicode. The case looks pretty clear to me.

Hello Hsing-yen,

As I said, I have worked on all this. I have not recently committed my changes. You will not yet see the work I have done on my local system. I'll let you know when I commit the changes and build a snapshot.

I have tested with BabelPad again, when I switch into italic and bold italic typeface, they looks still exist. In order to prove my mention, I have copied several special characters from Minbei and https://incubator.wikimedia.org/wiki/Talk:Wp/cpx/ Pu-hsien Min] Wikipedia test wiki in the Wikimedia Incubator to test, all of them can be found in their talk page for Main Page.

Most of this was already addresssed in
bug #44480: Bàng-uâ-cê letter issue
which I have worked on already.

On my local copy of the font, everything looks good, except the use of the "double overline" for a double-macron.

As I said before, this looks like incorrect use of the character. We need another solution. I would be willing to help with a proposal to the Unicode consortium.

The only other alternative I can think of, is to use two macrons. I could make that work, but it's ugly and also wrong.

Hi Steve,

I copied several texts written in Min Chinese romanizations from Wikisource multilingual, found several diacritical marks posotions incorrect in (bold) italic type:

For Gṳ̿ing-nǎing Lô̤-mǎ-cī
I copied several texts from Cho̤̿ng Si̿ Gi̿ (Book of Genesis) and Mǎ-tuo̿i Hŭ-éng (Gospel of Matthew) for test, found combining caron, combining breve, combining acute accent, combining diaeresis below positioned incorrect.

For Hing-hua̍ báⁿ-uā-ci̍
This also have similar sequences above, then combining vertical line above, combining acute accent (especially for ṳ, Cho̤̍ng-sa̤-gi̍ (Book of Genesis), 1:21) also have this problem.

Additionally, when I switched them into all caps style, these sequences also appeared, and ṳ̌ (found in Wikimedia Incubator) in regular type looks the same. Maybe they are also appeared in small capical type.
