下标/上标字符问题 (TouchGFX) [英] Issues with subsript/superscript characters (TouchGFX)

问题描述

我需要下标/上标字符才能正确显示 O₂、CO₂、m²、m³....

I need subscript/superscript characters for the correct display of O₂,CO₂, m² ,m³....

上标字符有效(m³，.. 没问题)，但如果我想有一个下标 2，显示器要么只显示O"而不是 O₂，要么在 O 后面显示一个hyroglyphic"字母.

The superscript characters are working (m³,.. no Problem), but if I want to have a subscript two, either the display shows just the "O" instead of O₂ or a "hyroglyphic" letter behind the O.

我检查了通配符范围，它是 0x02 到 0x2084.下标 2 的 Unicode 是 0x2082.
我还在通配符中添加了 ₂.

I checked the wildcard ranges, it is 0x02 to 0x2084. The Unicode for the subscript 2 is 0x2082.
I added the ₂ also into the wildcard characters.

我的代码:

void Screen1View::button_down_clicked()  
{
    Unicode::UnicodeChar list[] = {0xB2, 0};
    counter--;
    Unicode::snprintf(test_textBuffer, TEST_TEXT_SIZE,  "%d m%s", counter, list);  
    test_text.invalidate();  
}

请不要对 UnicodeChar 列表感到疑惑.我计划向 sprintf 添加多个 Unicode 字符.

Please don't wonder about the UnicodeChar list. I'm planning to add more than one Unicode-Character to the sprintf.

0xB2 是 ² 的 Unicode.这很好用.但是如果我写 0x2082 或 0x2083 就会失败.

The 0xB2 ist the Unicode for ². This works well. But if I write 0x2082 or 0x2083 it fails.

如果有人有想法，请告诉我:)

If anyone has an idea please let me know :)

推荐答案

您可能希望改用 Unicode::strncpy()，因为它允许您简单地将一个 UnicodeChar 缓冲区复制到另一个缓冲区.我认为你会有一些未定义的行为，因为 Unicode::snprintf 期望你尊重你指定的格式.

You may want to use Unicode::strncpy() instead since it allows you to simply copy one UnicodeChar buffer to another. I think you'll have some undefined behavior since Unicode::snprintf expects you to respect the format you specify.

我为我的排版指定了下标 2 (0x2082) 作为通配符，它​​给了我以下生成的 unicode(在 generated/fonts/src/Font_verdana_20_4bpp.cpp 中).请注意，您使用的字体文件必须支持您指定的 unicode 点.

I specified subscript-2 (0x2082) for my typography as a wildcard character which gave me the following generated unicode (in generated/fonts/src/Font_verdana_20_4bpp.cpp). Note that the font file you use must support the unicode points you specify.

 FONT_LOCATION_FLASH_PRAGMA
KEEP extern const uint8_t unicodes_verdana_20_4bpp[] FONT_LOCATION_FLASH_ATTRIBUTE =
{
...
    0xDF, 0xDF, 0x00, 0xE8, 0xDF, 0x07, 0xDF,
    // Unicode: [0x2082, ]
    0x00, 0x10, 0x00, 0x00, 0xE9, 0xFF, 0x9F, 0x00, 0x9E, 0x55, 0xFA, 0x09, 0x00, 0x00, 0xE0, 0x0D,
    0x00, 0x00, 0xF0, 0x0B, 0x00, 0x00, 0xFB, 0x03, 0x00, 0xC2, 0x4E, 0x00, 0x60, 0xBF, 0x01, 0x00,
    0xFC, 0x6C, 0x66, 0x26, 0xFF, 0xFF, 0xFF, 0x7F
};

并为屏幕 1 编写了以下代码:

and wrote the following code for Screen 1:

void Screen1View::setupScreen()
{
    Screen1ViewBase::setupScreen();

    Unicode::UnicodeChar buf[2] = {0x2082, 0};
    Unicode::strncpy(textArea1Buffer, buf, 5);  
    textArea1.invalidate();  
}

这在我的模拟器中给了我以下输出:

Which gives me the following output in my simulator:

如果我像您一样添加通配符范围":

If i add a wildcard "range" instead, like you did:

.. 我仍然得到生成的 unicode-point 的代码:

.. i still get code for the unicode-point generated:
