掃描使用 \field 時文件結束

Question

當嘗試引用問題中的條目時，文件中收到的完整錯誤訊息.log比編輯器的摘要更有幫助

(abstract-prob.bbl)
Runaway argument?
{Past, current and projected future population growth is outlined. Ba\ETC.
! File ended while scanning use of \field.
<inserted text>

l.33 \begin{document}

錯誤訊息上方的行提示您到底需要在哪裡尋找罪魁禍首。引用的文字「概述了過去、當前和預測的未來人口增長」。是abstract您輸入的欄位的開頭。

仔細查看該欄位（添加換行符以提高可讀性）

abstract = {Past, current and projected future population growth is outlined.
            Barring a calamitous pandemic, a further increase in the world's population
            from 7 to between 8.8 and 10 billion by mid-century is unavoidable.
            This increase is driven by high fertility in sub-Saharan Africa
            whose population is forecast to more than double in the next 40 years
            and by a modest rise of 23 % in Asia's huge population.
            Beyond mid-century, the range of plausible demographic destinations widens;
            much depends on fertility rates in the next few decades because
            they will determine the number of potential reproducers in
            the second half of the century.
            Vigorous promotion of family planning, particularly in Africa,
            is crucial to achievement of population stabilisation.
            Unchanged fertility implies a global population of 25 billion
            by the end of the century.
            In the next few decades the contribution of human population
            growth to global environmental change is moderate,
            because nearly all growth will occur in poor countries
            where consumption and emission of greenhouse gases is low.
            The implications for food production,
            and thereby water consumption, are greater.
            Much of the future need for food will be driven by increased
            numbers rather than changing diets.
            Loss of bio-diversity and natural habitats,
            degradation of fragile eco-systems due to over-exploitation
            and aquifer deletion are likely consequences.

該欄位在文件中的結尾.bbl如下（沒有換行符）

當 LaTeX在從文件中%讀取字段內容時遇到該符號時，我們會收到錯誤，因為該符號會將行的其餘部分變成註釋，這意味著看不到字段末尾的右大括號。abstract.bbl%}

這導致

! File ended while scanning use of \field.

錯誤。

解決方案是將%抽象字段中的符號轉義為\%。

由於大多數參考書目樣式abstract無論如何都會忽略該字段，因此最好從文件中完全刪除該.bib字段。（這可以由 Biber 即時完成，請參閱使用 biblatex/biber 時，書目輸入欄位出現百分號錯誤，但它是很多最好直接從文件中完全刪除該欄位.bib。%防止biber被摘要中的「%」字元噎住？。
