Support for Tâi-Lô and POJ characters (Taiwan Min)

[NightFurySL2001]

Tâi-Lô and Pe̍h-ōh-jī are transliterations used for Hokkien (Min language) and Hakka in Taiwan, which requires extensive support for accented characters and Unicode character combinations. (mentioned at https://github.com/damienleroy/PowerAccent/issues/10#issuecomment-1242434735)

The next tables are accented characters extracted from the two Wikipedia links provided :

• Tâi-Lô

Base letter/Tone 1	Tone 2	Tone 3	Tone 5	Tone 6	Tone 7	Tone 8	Tone 9
a	á	à	â	ǎ	ā	a̍	a̋
e	é	è	ê	ě	ē	e̍	e̋
i	í	ì	î	ǐ	ī	i̍	i̋
o	ó	ò	ô	ǒ	ō	o̍	ő
u	ú	ù	û	ǔ	ū	u̍	ű
m	ḿ	m̀	m̂	m̌	m̄	m̍	m̋
n	ń	ǹ	n̂	ň	n̄	n̍	n̋

• Pe̍h-ōh-jī

Base letter/Tone 1	Tone 2	Tone 3	Tone 4	Tone 5	Tone 7	Tone 8	Variant
a	á	à		â	ā	a̍	ă
e	é	è		ê	ē	e̍	ĕ
i	í	ì		î	ī	i̍	ĭ
o	ó	ò		ô	ō	o̍	ŏ
u	ú	ù		û	ū	u̍	ŭ
m	ḿ	m̀		m̂	m̄	m̍	m̆
n	ń	ǹ		n̂	n̄	n̍	n̆
o͘	ó͘	ò͘	o͘	ô͘	ō͘	o̍͘	ŏ͘

So :

    //Tâi-Lô
    private static char[] GetDefaultLetterKeyTL(LetterKey letter)
    {
        switch (letter)
        {
            case LetterKey.A:
                return new char[] { 'á', 'à', 'â', 'ǎ', 'ā', 'a̍', 'a̋' };
            case LetterKey.E:
                return new char[] { 'é', 'è', 'ê', 'ě', 'ē', 'e̍', 'e̋' };
            case LetterKey.I:
                return new char[] { 'í', 'ì', 'î', 'ǐ', 'ī', 'i̍', 'i̋' };
            case LetterKey.O:
                return new char[] { 'ó', 'ò', 'ô', 'ǒ', 'ō', 'o̍', 'ő' };
            case LetterKey.U:
                return new char[] { 'ú', 'ù', 'û', 'ǔ', 'ū', 'u̍', 'ű' };
            case LetterKey.M:
                return new char[] { 'ḿ', 'm̀', 'm̂', 'm̌', 'm̄', 'm̍', 'm̋' };
            case LetterKey.N:
                return new char[] { 'ń', 'ǹ', 'n̂', 'ň', 'n̄', 'n̍', 'n̋' };
        }

        return Array.Empty<char>();
    }

    //Pe̍h-ōh-jī
    private static char[] GetDefaultLetterKeyPJ(LetterKey letter)
    {
        switch (letter)
        {
            case LetterKey.A:
                return new char[] { 'á', 'à', 'â', 'ā', 'a̍', 'ă' };
            case LetterKey.E:
                return new char[] { 'é', 'è', 'ê', 'ē', 'e̍', 'ĕ' };
            case LetterKey.I:
                return new char[] { 'í', 'ì', 'î', 'ī', 'i̍', 'ĭ' };
            case LetterKey.O:
                return new char[] { 'ó', 'ò', 'ô', 'ō', 'o̍', 'ŏ', 'ó͘', 'ò͘', 'o͘', 'ô͘', 'ō͘', 'o̍͘', 'ŏ͘' };
            case LetterKey.U:
                return new char[] { 'ú', 'ù', 'û', 'ū', 'u̍', 'ŭ' };
            case LetterKey.M:
                return new char[] { 'ḿ', 'm̀', 'm̂', 'm̄', 'm̍', 'm̆' };
            case LetterKey.N:
                return new char[] { 'ń', 'ǹ', 'n̂', 'n̄', 'n̍', 'n̆' };
        }

        return Array.Empty<char>();
    }

Peh-oh-ji o dot tone 8 seem to be missing the dot.

Open it again. Issue not resolved. I had to revert the modifications. Therefore, I will create a release (2.0.0) without it, but it will be included in a future release. The pull request asks to:

• Display the language of the text alongside the flags.
• Introduce string instead of char for characters with multiple unicode codes.
