ThaiText

Unity Text UI for Thai language<br> I combined all useful tools (Thai lexeme tokenizer & Thai font adjuster) and support Rich Text.<br> Thai Text is inherited from Unity UI.Text and some features are also come from these packages.

Rich Text<br> The text for UI elements and text meshes can incorporate multiple font styles and sizes.<br> More information: StyledText

How it work?

1. LexTo

Lexto is Thai lexeme tokenizer. It's helpful for Thai text wrapping; automatic line-breaks. It requires lexitron.txt as Thai dictionary to work.

2. lexitron.txt

lexitron.txt is text file to contain Thai words for tokenization. This file must be in Resources folder, so it can be loaded. Normally, it should be at [Assets/DGN/ThaiText/Resources].

Note: lexitron.txt must be encoded that supports Thai characters. Default encoding is UTF-16LE

You can edit lexitron.txt file by

• adding new word in new line
• delete word
• add # at the start of word to skip this word

3. Lexitron Watcher

Lexitron Watcher is a file system watcher for lexitron.txt file.

• If lexitron.txt is not existed in Resources folder, it will import at [Assets/DGN/ThaiText/Resources]
• If lexitron.txt has been changed, it will update dictionary in Lexto.

4. Thai Font Adjuster

Thai Font Adjuster will adjust Thai fonts to be rendered almost correctly. Position of tone mark, upper vowel and lower vowel would be adjusted by surrounding characters.

Limitation

• ThaiFontAdjuster only can handle special fonts.

  • Font should have extended glyphs from U+F700 to U+F71A providing various position of Thai characters.
  • NECTEC National Fonts (Garuda, Loma, Kinnari, Norasi) already provide it.
  • Modified NotoSansThai containing extended glyphs is included in this package.
  • If you want to use another font, check it contains extended glyphs, otherwise glyphs have to be added to font by yourself.

• Adjusting position is not same as true-type rendered one with GPOS and GSUB support.

  • This library adjusts position of glyph at best with limited extended set of character. But without GPOS, ideal positioning is impossibe.

5. Tag String Parser

Tag String Parser is used to separate markup tags for support Rich Text feature.
