-/**
- * Parse the \c NumberFormatSeparators out of the given format string, with the expected number of digits.
- *
- * Different cultures have different ways to separate their numbers when they get really big. In the Western world
- * these are often called thousands separators which come every three digits counted from the back. The actual
- * separator differs per language/country. In Chinese, Japanese and Korean they add a character every four digits
- * counted from the back, and this character differs for each spot as it denotes "ten thousand", "hundred million",
- * etc. In the Indic numbering system (Indian subcontinent), the first separator is after three digits counted
- * from the back, but the next separators are given every two digits.
- *
- * So, there's no simple single parameter that you can add to the digit grouping character that is already
- * configured. The simplest solution is just defining what character to place between each of the digits, i.e what
- * characters separate each of the digits. These are the \c NumberFormatSeparators.
- *
- * To define these, you simply write a string of \c length zeros and then add any characters in between at the right
- * locations so the digit grouping is correct. When formatting numbers, it will start at the appropriate digit and
- * continue from there with separators.
- *
- * Examples of formats are "00,000,000,000,000,000,000" and "0000{NBSP}0000{NBSP}0000{NBSP}0000{NBSP}0000".
- *
- * @param separators The separators to fill; it will be cleared first.
- * @param format The format that is going to be read.
- * @param length The number of digits that are expected in this format.
- * @return An \c std::optional with the error message, or \c std::nullopt when the parsing went without problems.

- * Parse the \c NumberAbbreviations out of the given input string.
- *
- * In some places in the UI numbers are getting really big yet their exact value is not that important. For example
- * in the graphs of company values. For this you want more compact number, e.g. 123 m for 123.456.789. However, due
- * to the grouping of digits differing in different cultures, see \c ParseNumberFormatSeparators, there are many
- * different ways of grouping digits.
- *
- * This function builds up a lookup table of these abbreviations by power of ten. The input will be a list of
- * definitions per power separator by a pipe character (|). Each definition is the power of ten and and the
- * associated number format with DIGITS_IN_UINT64_T - power digits, separated by the equals sign (=).
- *
- * For example, for English it defines every third power of ten with subsequently smaller number formats:
- * 3=00,000,000,000,000,000{NBSP}k|6=00,000,000,000,000{NBSP}m|9=00,000,000,000{NBSP}bn|12=00,000,000{NBSP}tn|15=00,000{NBSP}Qa|18=00{NBSP}Qi
