## Introduction A pixel-based UTF-8 printing program  > $\color{red} \bf Note:$ > The CC compiler reads UTF-8 characters as '?', > `print("Hello World")` has the same effect as `print("????")`. > To fix this, read files in `"rb"` mode for proper input handling. ## How to Create Fonts - Font files should return a table where keys are UTF-8 code points, and values are corresponding character bitmaps. - Each bitmap is a table of equal-length strings representing a 2x3 pixel grid defined by Computer Craft. To use the bottom-right pixel, subtract 128 from the char code to invert `backgroundColor` and `textColor`. - A single font file may contain bitmaps of different sizes, but it **must** include a bitmap for 'H' (ASCII:72) to indicate the maximum height of the font. - The final output uses the maximum bitmap height in the FontFamily as the baseline for bottom-aligned text. - The FontFamily **must** include a '-' (ASCII:45) bitmap for potential word splitting during auto-wrapping. ## Technical Details - `require` a fusion-pixel-12px font consumes approximately **10.5MB** of memory. - `require` a fusion-pixel-8px font consumes approximately **6MB** of memory. - 8px characters occupy 3 rows vertically, while 12px characters occupy 4 rows. - Fonts are sourced from fusion-pixel-font.

## 介绍 一个基于像素打印的utf8打印程序  > $\color{red} \bf 注意:$ > CC 编译器会把utf8字符读作 '?', > `print("你好世界")` 与 `print("????")` 的效果相同, 可以`"rb"`模式读取文件以设置输入 ## 如何制作Font - 字体文件返回一个table，键值为utf8编码，值为和对应字体的bitmap。 - bitmap为一个包含等长string的table，string中的char属于computer craft定义的2*3像素点阵（如需使用右下角像素，将char的码值减128表示反转backgroundColor 和 textColor） - 单个字体文件中可以有不同尺寸的bitmap，且**需要**有'H'(ascII:72)的bitmap表示该文件中最大bitmap高度 - 会以FontFamily出现的最大bitmap高度为基准，最终输出下对齐的文本 - FontFamily中**需要**'-'(ascII:45)的bitmap以供自动换行时可能的切断单词使用 ## 技术细节 - `require`一个fusion-pixel-12px字体，大约消耗**10.5MB**内存 - `require`一个fusion-pixel-8px字体，大约消耗**6MB**内存 - 8px字符实际占用3格高的字符数, 12px字符实际占用4格高 - 字体来自 fusion-pixel-font
